my biggest pieces of advice for combat encounters:
1. make encounters have more than 1 enemy, preferably 3 at least, because action economy heavily favors the side with more turns
1a. if you do run a single enemy, give them legendary actions and at least one legendary resistance
2. combats are at their best when there's some dynamic element to them, some obstacle besides the enemies themselves
3. it's often nice when there's a goal in a combat other than just death matching it. like, if you need to get a specific object, or something. you don't always have to do this, but it makes things more fun.
4. group enemies who use the same statblock together in initiative, it'll save a lot of headache
