Connect Nighthawk M1 to Orbi RBR50 to GS108 Switch

Hi All. Hoping for some help. I've seen some great advice and am optimistic someone will nail this one.

I am trying to connect a Nighthawk M1 to an RBK53 Orbi, but I also have a small network from a GS108 switch. Hate to say it, but I have some devices that I can't go with wifi. Call me old school! I read a posting from Pridal2008 that had a similar config without the switch. He asked how to best connect / config the Nighthawk to the Orbi. ArodiD had an awesome response:

Option 1 (Bridge Mode):

- Enable IP Passthrough Mode on the MR1100 (Settings>Setup>Mobile Router Setup).  Steps are also detailed in the User Manual.

- Nothing needs to be done on Orbi router side.

Option 2 (DMZ)

- Set a static IP on the Orbi router (i.e 192.168.1.45) - Advanced Settings>Setup>Internet Setup - https://kb.netgear.com/31140/How-do-I-manually-enter-a-static-IP-address-for-my-Orbi-router

- Set the Orbi's static IP as the IP in M1's DMZ (Settings>Advanced Settings>Other - enter 192.168.1.45 into the IP field).

Option 3 (Enable AP mode on Orbi)

- Enable Access Point mode on Orbi Router - https://kb.netgear.com/31218/How-do-I-configure-my-Orbi-router-to-act-as-an-access-point

So here's the add on:

Should the Nighthawk connect to the Orbi first or the Switch? In other words - Should I connect the Nighthawk to the Orbi Network In then Orbi Out to the Switch or the Nighthawk to the Switch to the Orbi Network In? And, given the above which option (1, 2, or 3)?

I'm thinking Option 1 and go Nighthawk -> Orbi Network In -> Switch to run the local LAN.

Any thoughts, comments or humor?

Thanks!
