With these settings, you should be able to connect to HDMI and mDP external monitors. Enabled Switchable Graphics (Check) Discrete Graphics Controller Direct Output Mode - disabled (uncheck) TB3 is not fully supported yet I think, so it's not hot pluggable. You'll need it connected before booting to access it. Go with the DW1560, minimum patching require. Just need 4 kexts and you're good to go.

Choice is extremely limited as far as M.2 cards are concerned: DW1560 (BCM4352) -> patch required DW1830 (BCM4360) -> works OOB DW1820A (BCM4350) and related -> patch required but probably best avoided given the amount of headache & trouble it's given to users; no guarantee it'll work... I know of no other M.2 cards that are fully supported. There are Atheros cards of course but Mojave dropped support for those even though Atheros cards that worked up to High Sierra can be re-used under 10.14 once the Atheros40 kext from previous macOS release is re-installed. This being said, M.2 cards based on AR946x/AR9565/AR9485 chips are not supported to the full and only operate at limited rate. They require a re-written Atheros40 kext.
