There are a few options, but the least expensive is with an Era 100 with the line in adapter. If you have the room, this would be a great option because you are able to add a second 100 for true stereo sound.
The other option would be the Port. This option is great if you do not have room for another speaker or two. You can set the Port to auto play to any speaker you select, then group it wit the rest of your speakers.
I prefer a wired connection over wireless.
A couple of comments. If I recall correctly, the first generation of the Move was incapable of sharing the Bluetooth signal across the network, that changed with the second generation. None of your other speakers have a Bluetooth receiver built in.
As to connecting to your Move, you should be sure that any other device that the turntable is connected to is off (Bluetooth), as Bluetooth can only handle a single connection at a time, so if the turntable is currently connected to your Marshall, it won’t connect to your Sonos.
Finally, in order to get your turntable’s signal into your Sonos ecosystem, I’d suggest a slightly newer Move 2, or a Roam, or any of the newer speakers that have Bluetooth and can share that input across the Sonos. Or, my own preference would be to abandon Bluetooth as a connection method, and wire the turntable directly to a Sonos line in, which is available on many devices…none of which you have, unfortunately.
There’s a good resource for turntable connection here, too.

I have a similar setup.
I'd probably utilize the move along with the play 3 elsewhere, purchase a Port connected to your speakers (wired not Bluetooth) & purchase a to also connect to the Port, have the soundbar along with play 1s for a 5.1 configuration for both movies and music. You can create a group of all of that to tie it all together.Some would argue to make a choice of what you play the most and only pair the sub to the Port. I leave them all in one group though and sounds great
Another option would be similar to mentioned above is an Era 100 or play 5 which has internal phono jack so you don't need the Port.
