I relate to this pretty hard. I am lucky enough that my wife is fairly tolerant of anime weirdness since she is an old school anime fan as well (though not as tolerant as I am). However, friends that have asked me for recommendations in the past have been turned off by things that hadn’t even phased as weird at the time. It has caused me to think about these kinds of things a bit differently. Like your partner, I am also a big fan of Bob’s Burgers, GBBO, and Ted Lasso, so here are a couple that come to my mind with what you have written in mind. I also marked the ones that I watched together with my wife and she liked them.

• Usagi Drop (wife approved) - A story about a salaryman that finds himself having to adopt a young girl after a death in the family. It deals with the realities of being a single parent in the harsh working culture of Japan as well as how to handle caring for and connecting with a newfound daughter. I wrote about this series in a recent clip post I made. This might be a bit of a controversial pick because the manga continues the story and it becomes less wholesome. However, as an anime-only, it is incredibly wholesome.
• Tonikaku Kawaii - This is a romance about two people that have what seems like a fated meeting and end up married quite suddenly. The show follows their daily lives as they figure out how to have a relationship. Despite the sudden marriage plot point, the romance is entirely wholesome and neither character ever regrets or second guesses the choice. It is mostly SOL, so it might end up a bit on the boring side, but incredibly wholesome.
• I’ve Been Killing Slimes for 300 Years - This is an isekai about a woman that is so overworked in her first life that she dies. She is reborn as an immortal witch and decides to live in a cottage in the countryside, killing slimes occasionally to provide enough income for her needs. Turns out that if you do that long enough, you become super strong. Super comfy fantasy story that isn’t too boring imo.
• Campfire Cooking - Another isekai that has a strong focus on cooking food. I really like cooking and do it a lot, so your experience with this show might differ. When I was watching this one as it aired, I ended up making a lot of Japanese food to eat (so many tonkatsu) because it always made me hungry. There is an overall plot, so it isn’t just a story about camping out and cooking, so it should hopefully not be too boring.
• Natsume’s Book of Friends (wife approved) - A story about a boy that is able to see yokai thanks to an ability he inherited from his grandmother. This series is mostly structured as a yokai-of-the-week series with each episode being a mostly self-contained story. There is an overall arc and cast of characters, but nothing too dramatic and very little anime weirdness that would turn people off. The only anime weirdness I can think of is humor around the partner yokai’s love of sake.

There are a couple others that I see recommended as wholesome quite often that I have not seen, so it might be worth checking others’ opinions first: Yuru Camp, A Place Further Than the Universe, Non Non Biyori, Flying Witch.

Good luck!
