I'd really not like spamming this again but I should strongly emphasize, stay away from snap and gnome, you would be completely put off computing if you are escaping modern Windows and come to Ubuntu and then experience this nonsense the first thing. They are the same tarpit of user hostile software requiring you fighting your computer 24x7. Some people might disagree about gnome perhaps, but they have a long and well documented history of nastiness, removing features, rewriting everything, deliberately not solving certain bug/feature requests for several years. And since they are de facto in control of gtk now, its also bleeding there too. There are talks of killing theming in gtk 4/5 for example.

And snaps are basically an all in one packaging solution, the main evil relevant to you are forced updates and officially speaking there is no way around it last I checked, at best you can set a grace period. Also they put files in weird locations so good luck trying to edit their settings, etc.
