If you're worried about client behaviors you could disable 802.11ax features on the MR86's to remove the extra IE's in the probe replies and assoc frames coming from those AP's.  Those will make sure your client does not see any additional features on those AP's.   And if you really want to be sure, just group the 86'es together in one area so you don't constantly roam from 84 to 86 back to 84 etc.. any difference in behavior will then be minimized to the times you do cross from one AP type to the other.   In a mixed network you won't have NBAR but you are not using that right now so you won't be missing anything. ...

Initially both the LAN and WAN will be linked across all ports so the WAN should find the internet via the LAN.  Make sure nothing important is connected to the MX before the config has applied!  ... View more

You'll want to build an access policy that uses RADIUS and 802.1x. For all the other configurables, have a look at the doc @ww provided and make a call on what suites your environment best.   As for the auth based on device certificate and MAC address, those policies are configured on the RADIUS server as it will be performing the checks. It will then return and pass or fail, along with the corresponding vlan attribute for that device to be placed in. ... View more

The QoS settings on MS switches don't need routing so the outbound queuing is respected for matching traffic.   However you cannot move your audio LAN up to the MX if you require multicast support since the MX itself does not have IGMP querier nor PIM support.  That task can only be done on your MS switch L3 interface.   So it's best to just match the traffic types on your MS switches or just trust what's coming from that VLAN and make sure your needed DSCP values are present in the DSCP to CoS queue mapping section. ...
