Lutris and PlayOnLinux are quiet simple to use but I have been using as main OS for a few years now. So this reply maybe biased.
I recommend Steam though (sounds strange, right!)
I add executables as “non-steam game” and set proton in the properties. It will run the exe under the given proton build.
Note: there is a bug that happens when adding a non-steam executable to steam. If there is any space in the path, it will add the path till the space. Just edit properties to add the file again. It will add complete path. Just open the properties for the added item to see what I mean.
If the buttons were larger, I can see this as a good phone for elderly.
I live in middle Asia and I still see elderly people using old school phones. Nokia isn’t as dead as you might think ;)
