Don’t do a transition..use sanded caulk in a tube to match the grout of the tile. Transitions trap dirt and are not necessary for what you are doing. The expansion of the wood floor is a little of a concern but the sanded caulk will stretch enough to keep things sealed. Set the wood floor against the tile with a “nickel gap” and let it straighten itself out over the first few boards.
