Morrowind is one of my favorites! Graphic Herbalism is nice, but the DB and Sosltheim fixes are the only necessary ones, atleast for OpenMW.
Have fun! You’ve probably already heard this if you’re aware of the bug fix mods, but if it seems like you’re missing every other attack, check your stamina and make sure you’re using a weapon you’re character has the skills in. A low stamina bar affects every skill check, and that iron dagger in the census office often trips people up if they try using it without taking short blade as a major skill, as an example.
I love Morrowind, but it doesn’t do the best job of walking you through how combat works unless you read the manual, so I thought I’d mention it just in case :).
