I think you should reconsider the XNA target IMHO.
Monogame is api compatable with XNA and compiles seamlessly for all platforms (iOS, Android, MacOS, Linux, Windows, PS4, PSVita, Xbox One, Switch). It is also the fastest build target.
I can currently compile a monkey game for XNA, do 2 find/replace and build/run the game with 0 errors with MonoGame.
Personally, I believe that XNA/android performs better and has more features than the current Monkey/Cerberus Android target.
Not only is the Xna target not outdated, It's superior.
