My frame is a 2017 Trek Domane with BB86 — will this work with SRAM Force 22 GXP cranks?

Yes — SRAM Force 22 uses GXP spindle and this PressFit GXP BB installs in BB86 shells. This is the correct bottom bracket for that combination.

Should I upgrade to DUB when replacing my GXP bottom bracket?

Only if you are also replacing your crankset. DUB and GXP are not interchangeable spindle standards. If keeping your GXP crankset, replace with the GXP BB. If upgrading crankset, switch to DUB.
