I can’t believe it’s taken me this long as an early adopter of gnome-multi-term (RIP) on Gnome but I’ve finally looked into tabbed terminals on windows.
For putty, there is tty+ and putty manager. Putty Manager seems better, but tty+ also works with kitty.
For cmd.exe shells as well as cygwin bash shells, there is console2.
