If the scratches are easily felt by running your fingernail over them then T-Cut won't do any good. A machine polish will be in order, unless the scratch has reached the colour coat - in which case it's time for a paint fill/repair.
By all means start with a hand polish, if that doesn't work it's worth trying a compound and, if that still doesn't work, a machine polish (try a DA if you want to do it yourself). Sanding should only be done as a last resort and huge care needs to be taken; remove too much clearcoat (we're talking microns here) and your looking at a respray. Always work up slowly to the more aggresive options. Once sorted (assuming it doesn't need paint repair) gradually work you way back down to a light polish, this will ensure no swirls are left from heavier polishing.
Be aware of gimmicky scratch removers, most (if not all hand applications) contain fillers and only temporarily mask the scratch.
Good luck with it.
With reliability will ultimately come monotony.....
