I’m not enjoying fighting enemies at a much higher level than I am.
There's a lot of difficulty adjustments you can do at any point from pause menu
So make a save, go there, and see what it's like. Maybe you decide to lower difficulty and force thru it, maybe you reload and go level up.
But despite its flaws, Starfield gave a lot of player freedom. If you want to grind levels, adjusting difficulty adjusts XP earned. So you can cheese some settings to max XP gain and quickly get up to level 30.
And if you're on PC you can always just use console commands to level up.
