RaceMenu can be used with any mods that customize characters.
For males I use Better Males. Geonox faces and flavored soul body. However this makes it NSFW. There is an underwear version of the body. Note there is a very slight neck seam with Better Males, but I haven't found a male mod without them. Lower complexion (clearer skin) makes this problem less visible.
For females, I use UNP Blessed Body. This is NSFW. I'm not sure a SFW variant of this. I also use Mature Skin Body and Texture to make the women not look as much like teenagers. Also NSFW.
For the face (both sixes), I use SKSE Better Makeup (make sure you do the tint texture resolution tweak in skse.ini). I also use Northborn Scars and XCE Warpaints.
All of this was taken from Neovalen's SR:LE guide.
Edit: Also a mod called "Brows", one called "Beards", "Superior Lore Friendly Hair", "The Eyes of Beauty".
I'm sure I'm missing a few. Google SR:LE and check the guide for more info.
Edit 2: Also, if you use UNPB for females you need the armor replacers. There are a bunch. Again, SR:LE has details on this.
