Use Nexusmods and their Vortex mod manager. It simplifies it a lot, though you may have to watch a quick tutorial video or two. It’s nothing that you won’t learn, though.

Certain other games may have other mod loaders just for them, that you can use. KSPs CKAN comes to mind, or Curseforge for Minecraft. A lot of games handle mods through the Steam Workshop.

In the case of using mod loaders most of the stuff you will have to do yourself will be limited to keeping mods updated, resolving conflicts, and managing load orders (where applicable).
