Welcome to Ljs
Depending on how thick it is your slab may not be ready to use for some time longer than a few months as a rule of thumb wood needs 1 year of drying time for every inch of thickness depending on where and how is stored to dry and what kind of atmosphere it s in. , If you make a table out of it before it s dry you risk the possibility of the top cracking or twisting. As far as finishes are concerned Arm R Seal is a strong durable finish it is oil based so it will bring out the grain and color of the wood without any additional finish.
