Yep. The third one is especially good.Since no one else has mentioned them, the Monster Manual Expanded books (I, II, and III) are excellent monster books available on the DM's Guild (the first two with PoD if you want, with the third, which was just released, with PoD later in the year), all with loads of monster variants on MM, VGtM, and MtoF monsters, as well as some updates for creatures that haven't made it to 5e yet...
