It’d probably depend on the game, but see if there’s any source ports for the games in question. DSDA Doom, for example, adds modern wide-screen support to classic Doom and has heaps of fantastic options for different compatibility levels for different custom map sets. GZDoom is also an option if you want gameplay mods (shame it’s so inefficient lol).
You can also see if there’s any wide-screen patches for your games on the PC gaming wiki.
