When I was distro hopping to discover what would be my daily driver I found POP annoying to handle some of the more day-to-day tasks A lot of unnecessary fluff and handlebars around the place. I feel like Mint doesn't give you training wheels. Rather it just teaches you why things are the way they are. For example on the first-time boot PopOS. when prompting me to update some programs, it failed and crashed the package manager leaving me clueless and forcing me to open it again and sort out that I needed to update the package manager. Meanwhile, over on Mint's first-time boot, the update manager refused to let me continue with updates until I updated the package manager FIRST, then explained to me what each symbol meant and how to update things. I may have already known what everything did, but it was still far more helpful in the short term and a cleaner experience.

I can see that perspective, but I think the word 'beginner' still makes it sound like people want to paint Mint in a poor light. It sounds elitist ya know? Perhaps a better word for it is reliable.
There was a flatpack release for the ED market connector awhile ago, I have no idea if it's still functioning (i have gotten in the habit of doing it manually too) but you might want to check it out. https://flathub.org/apps/io.edcd.EDMarketConnector
Actually, I have had minimal problems overall. The only games I have been unable to play are those with 'Easy Anti Cheat'. But more often than not I can click install on Steam and start playing games first try just like on Windows. I do still check tho on protondb if anyone else has had issues getting the game to work just out of habit.
I was actually thinking about that, I might do the same if Ubuntu decides to move away from support deb packages like they said they would.
Have you tried the Lutris wine preset for it? https://lutris.net/games/clip-studio-paint/
