The biggest danger in Morrowind modding is not having moderation. Be very picky.
What I don't get: most of this list is small cosmetic changes that haven't been updated for >4 years. Apparently nobody has thought of combining them into one of the larger texture packs that is already there? Anyway, now I'm so far down the list that there's really no going back.
Personally I will direct you to the nexus. Most of the current modding community in english resides in the morrowind modding community server at discord and hosts in the nexus all of their creations.
Also there is a lot of modern work coming from the english and russian speaking communities but they are usually hard to keep track of unless you stay on the top of things but some solid work will always be a staple even if its old.
I am currently on a project with a friend in trying to port some of the oldest mods from modding history/fliggerty/old modders to the ligth of 2020/2021
I for example, as an Argonian exclusive player ported this one: https://www.nexusmods.com/morrowind/mods/48668
It is an Old mod by Adul but simple and easy to use and install, made some cleanups of the old mod (which was very dirty) and made it more modern mod standards compliant,
In particular I find the nexus an extremely easy to use and wide scope modding platform and an excellent repository for Morrowind Mods, try it! :D
