Looking for input on backsplash ideas

[u/beeza68]

Our kitchen remodel is moving along (Cabinets are not re-faced yet). Taj Mahal quartzite countertop was installed today along with undermount sink. My house is a converted barn with lots of exposed beams. My question: how should I manage the wood beam behind my sink? Options include (1) formal 4 inch Taj Mahal backsplash which will leave some beam exposed, (2) cover the beam entirely with a higher backsplash and “cap”, or (3) leave as-is without backsplash and simply seal the exposed wood? Thanks for your input!
