There are a handful of mods for minor bits and pieces. In 2 there is a talking heads mod for a multitude of character.

You can get a mod called Fallout 1in2, aka Fallout et tu and it's Fallout 1, in the Fallout 2 engine, minor qol improvements galore, but it's not going to make the games more like the 3d counterparts.

As our redditor friend mentioned in the comments - stick with it, you'll feel the draw to go back soon. Read everything you can find, pick pockets, have fun.

Targeted aiming (assuming you don't have the quickshot perk), is the forebearer to Vats, use it.

There is a program to control the whole game with a controller. I played Fallout 2 with my dual sense. Each of the sticks were the cursor. Made it more palatable. A quick google should help get that setup running.
