the effect of utc vs local time would always jump by your timezone offset to utc which is usually whole hours and some timezones have half or quarter hours or such, IMHO it shouldnt cause clock “drift”, that is unless thats a feature of windows time handling when the time has a huge offset.
ntpd used to slightly adjust the clock only if the offset to remote servers is something like few seconds and would “step” to immediately correct the system clock if its larger.

i see two things, boot entries and the hardware clock.

AFAIK with uefi windows wants to be the first entry in uefi boot list, otherwise it will set it and overwrite the boot mechanisms but one can set the entry to be first but disabled, thus uefi boots the next active entry every time while windows doesnt overwrite the boot settings during updates. i tested this to some degree, but i do not boot windows on that machine often enough, so i dont know what really happens on updates. i got this info from the evil internet and it sort of made sense while not harming at all so i did it that way and it used grub all the time up to now.
take care to have a backup of boot entries to quickly restore them in case microsoft overwrites things without beeing asked to.

second things is rtc clock.
in the past windows stored local time in the hardware clock while linux usually set the more sane utc value. if these settings concurrent, there will be surprises and time jumps depending on what bootet last and updated the hw clock.
i guess microsoft will rather stick to the option that is less sane and causes overall more problems, so i guess you should have a look at it, and if there are problems, either set windows to put/expect utc or linux to put/expect local timezone to/from hw clock.
i might be wrong and they already solved the problem when designing uefi definitions, but better look at it or at least observe it somehow.

pidgin english.

let me clarify one important thing here:
“favorite” can have be of limited meaning as in:

to me it is “the favorite” language/accent i use as an example about languages where i do understand several of their accents well enough (american english, british english and australian english) that i am sort of confused to not be able to distinguish even syllables when someone talks in pidgin-english.

in other words: i dont like it at all.

so its sort-of-my-favorite regarding ONE single use only: as a negative example XD

i would suggest to create aliases for every single company/platform/account you migrate to a new email account and never ! use your actual new address, always use an alias for all emails then. maybe choose a provider where the real email adress can be changed while all aliases stay the same (try it out before migration), thus when it is leaked once, you can also change this one.

there are email clients that can automatically answer with the email alias the mail was sent to, so that part should be easy (i still use thunderbird that cant do it)

every time some CEO wastes your precious time by saving on admin hours for the sake of his fourteenth golfcart hence company leaks YOUR data to some spammers, you immediately know which company was the one leaking AND you can create a new alias, change it at the company and deactivate the old one thus beeing in power of stopping spammers as well as longterm their helpers = you can stop the CEOs of poorly managed companys that managed to leak your data from stealing your time by leaving that company after x leaks.

if thats not a win, consider that once your main address was leaked, no matter how, the amount of time to change it again would be troughly the same as migrating now. just keep that in mind when migrating.

if you want to make groups to have lesser aliases, thats ok, but i suggest to still never use the real address, always make aliases.

i live without spamfilters for so many years now and got less than 20 spam mails per year within the last decade (also without any false positives). most spam mails reach me for a single leak until i find time to change it, so even the max number of 20 werent 20 leaks that year but one (and public whois address that got harvested)

better own your domain and dont host it in the US for security.
i could suggest hosting your domain at pananames or domainscanada, but i dont know if they also provide email services.

pikvm uses software to emulate keyboard and ie. usb drives, NIC, etc that are then controlled via network/UI, it can fit on a raspberry pi 2w zero and connect via wifi.
however usb usage is limited to a few simultanous things and i dont remember what all was possible at the same time, but to circumvent these or OS limitations (where afaik sometimes a keyboard could not also act as a storage device or such) pikvm people suggest to use a raspi pico to emulate the keyboard with a separate cable.

however to actually connect the rpi zero usb port (that can be host or device, but not at the same time) it is advised to use a usb cable where the 5v wire is cut/disconnected to not somehow damage one of the power sources.

cost: ~20$ for the rpi zero 2w and a cut/soldered micro usb cable to NOT connect the two 5v power sources.

if it fits your purpose i cannot say, but my experience is that it worked fine with PCs (even through a kvm switch but with some quirks) and other raspi’s but i never connected it to a tablet or smartphone.

edit:
you also need a spare sd card.
and a direct connection from the notebook to the tablet depends on the usb port of the notebook. usb ports on computers are usually host ports while keyboards etc are device ports. one cannot usb connect two decive ports or two host ports together, but special hardware exists that can switch its role (and somehow needs to be told to do so) on mobile phones the ports detect what is plugged (PC, a keyboard etc) and the port is then configured to be a device (plugged into pc) or host (when a keyboard is plugged in) or maybe just configured for charging.
i dont know which part of pikvm does the configuration for the port to be a device, but without the specialized hardware (that the raspi 2w zero has) it would not be possible. notebooks usually didnt have such ports, but that might have changed meanwhile with usb3 or usb-c or just evolution and cheaper both-role capable chips.
