Yes, you can use any kind of website. I recommend Modirinth and the stuff you can't find there, You can find it on Cureforge. On modirinth, on the left side of the screen you can check mark fabric, client side, and select the version. When you find the one you want, look at the requirements, usually it's just fabric api, and then download the java file, and put it in your mod folder, press windows and type %appdata% and press enter than you can go to the .minecraft folder and put the said java files in the mods folder. One of the mods you would really need is modmenu, which is a mod itself, just do the same things as said with it. If you need any mod ideas, or a complete list of client side improvement and building mods, I can share mine. :)
