I think a lot would depend on what’s your style, where are you going to be cycling? There are some general categories like commuter, mountain, road, recently more popular gravel which now days are more like mountain bikes from 90’s. Most important is to start riding wherever you are, whenever you have time. Pick something you can afford and won’t break your heart if you drop it (like 10K super bike).
Most of the time if I ride it’s in the morning. For me its the easiest and most reliable way to plan and execute before day starts. There is also this feeling of accomplishment after the ride and it feels great the rest of the day.
I haven’t been able to go out this weekend yet but I’m right there with you in Bay Area virtually. Did double Mt Diablo virtually ride yesterday!
