WPA/AES-CCMP should be OK for most purposes.

Honestly I'm not really sure what Tomato is doing for "Wireless bridge
mode," a quick google didn't turn up an answer.  It would be
interesting to see some wireless frame captures from the setup.  If
it's doing some WDS 4-address mode, then that's great.  If not, you
may have some problems reaching some machines behind the client

Sounds like "Wireless client mode" is running two different IP
networks and routing at layer 3 between them (i.e. the network behind
the client router would be on its own subnet compared from the AP
network).  This mode will work with any AP.

Yes, this is something 'extra' that mesh could offer (if you wanted --
you can also just bridge the wireless traffic onto an ethernet LAN
like you are doing, without running a second AP).  Mesh also has some
better encryption facilities built in.  But, I'd say having an AP that
supports mesh is highly unlikely unless you put openwrt on it yourself
and the hardware is Atheros-based.
