Need advice regarding barrel aging / fermenting

Hey I just got this virgin charred American oak barrel, I've tried to see more barrel information but it seems to be all scattered around forums in the net,is there any place with consolidated information? And what would you recommend being my seasoning drink, I was thinking to either age or to second ferment my cider/ beer, i also tought on making this a vinegar barrel but i think it could be a waste, at least rn. Any and all comments are welcome !

Best regards !
