Removing scratches is a bit of a misnomer. You can remove a scuff as long as it’s not gone though the paint, if you can feel it with your fingernail then it’s too deep and needs filling / sanding / painting.
Farcela G3 is good. Buy the complete set, the scratch remover is the most aggressive and will sort the scratch itself, then paint restorer is less abrasive and will polish the paint back to a good finish. Then wax it (hard wax is better though)
T-Cut on it’s own is really quite aggressive and will leave the paint dull afterwards.
If it’s a dark colour then the coloured fillers work quite well. Poorboys do one called black hole. It’s a step between polishing and waxing and is adding a dark filler material which fills all the microscopic marks in the paint so the light doesn’t reflect off them making them invisible.
But after all that, if it’s more than a very light mark then you really need to get a professional in to sort it if it bothers you.
