Surprised none of the other commenters have mentioned zellij. I work across windows (WSL) and linux so really like having the same set up for both, which means no Ghostty/Kitty since they don't support windows.
Zellij is a lot smoother and nicer looking out the box, and its key shortcuts are pretty intuitive. There's a lit of advantages to not having an extra layer, but zellij + alacritty is definitely worth having in your list of options!
