This.
Though, I will use a CPL or ND filters.
If you really do want a filter to protect it, just get a clear filter (multi-coated to reduce flare). There's no point in getting a UV filter. Nearly all camera sensors have built-in UV and IR filters and calibrated to them. Adding a UV filter will never improve image quality. And UV costs more than clear, anyway.
UV filters are products of the film era. Where 35mm film is sensitive to UV light. If you are shooting film, or if you removed the filter from the sensor, then yes, use it.
