is basic fantasy roleplaying game good if i like 5e but want a lighter game?

pretty much my title!!! i like the vibe and feeling of 5e d&d where it's kinda heroic and high fantasy with lots of magic, but i just feel quite drained/tired after dming a session of it and i notice we seem to have rules arguments we dont have when i dm other games like call of cthulhu!!! so i've been trying to look at other fantasy rpgs instead but i feel so overwhelmed by all the choice!!

is basic fantasy rpg a good choice for me? or does anyone have other recommendations!!!

edit: THANK YOU for all the suggestions everyone!!! i really appreciate it!!!
