TBH at least for the moment there seems to be very little to no use since you can go through the Alpha Island just fine without ever putting points on to it.
You can go through the Island without putting points into anything in particular. I put all my points into WIT one time and only found a bunch of level 1 rings for example.
It is more fun to put your points in FIN/INT/STR depending on your preference and add enough memory that you cant get through gear to cast what you want. Otherwise the fights go on too long and you keep dying.
However (back to Civil Abilities) unless you want to traipse to a vendor you need Loremaster. Unless you can find the key you need Thievery. Unless you want to see a sparkly clover leaf twice in a playthrough you need Lucky Charm. I savescum persuasion checks so I don't know about that.
I can't pick up a heavy item (like a 150kg painting) with Telekinesis if I don't have the strength. I can move them (why would I want to do that) but not pick them up. Perhaps I'm doing it wrong.
You can however pick up stuff faster. If you don't have it you have to wait for the animation before you can pick up another item. This is boring if there are dozens of items to collect. If you do have Telekinesis you can pick up things at a reasonable rate.
So, I don't put points in it but I do use the Sebille (with lucky charm) and a pair of gloves or ring for telekinesis to pick stuff up.
Grab an item or character and pull or push it away or towards you, dealing physical damage to it. This will also deal physical damage to any object the item or character crashes with a chance to stun living things.
You could do that in DOS:EE. You could put 50 water or oil barrels in a chest and hit someone. The damage was based on the weight of the chest so if it weighed thousands you did thousands of damage.
I would humbly suggest that that is cheating.
