StravosSMP is a survival server that tries to keep the vanilla feel but adds some quality of life stuff. It runs on the most up to date version listed as 1.26.1 and you do not need to download a modpack since it is all server side.
The big things people talk about are graves so your items do not just vanish after you die and VeinMiner so you can clear ore veins faster. There is also a live auction house so players can buy sell and trade items from anywhere.
Getting around is easier too since you can use sethome and tpa. The server also says it is fair with no buy to win ranks so everyone starts with the same features.
