Which window manager do you use?
Sway had the better, though often tedious, WM tab solution that I've tried. Niri had a useless one.
I really tried to love sway splits and tabs for terminal windows. But I finally admitted I'd rather just alt-tab to a few different terminal apps, each with its own concern (maybe one per project, this one for my remote machine), and best of all, each with its own internal tabs.
That said, tabs in kitty and tmux, for example, are so basic that you don't necessarily lose much if you were to use WM tabs instead.
On the other hand, tabs in iTerm2, Ghostty, Cmux, probably macOS Terminal -- a bit more powerful and intuitive since you can do things like drag them, and they can show info like terminal state. And in some of those apps, they can be displayed vertically which is my favorite.
