Honestly, I don't think you are going to take that much time to get used to fedora based distros since in my experience the only thing that ended up changing was the name of the package manager and the faster updates.
I would recommend that you use more up to date distros since gaming in Linux has been having fast-paced performance updates and with the new proton stuff which is relatively new and is only to get more patches because valve is investing on it. So picking up fedora might be a good choice since its more up to date and it isn't that different to debian compared to more minimal/advanced distros such as arch and void (but being more advanced as a lot of percs that simpler distros don't have).
