Feedback:
Multi-queue allows network performance to scale with the number of vCPUs and allows for parallel packet processing by creating multiple TX and RX queues. It would be nice to add some information about these tunables when on ESXi using vmx.
For example, on an 8 vCPU VM:
Edit/create the following file
/boot/loader.conf.lcoal
Add the following content
hw.pci.honor_msi_blacklist=0
hw.vmx.txnqueue=8
hw.vmx.rxnqueue=8
hw.vmx.txndesc=2048
hw.vmx.rxndesc=2048
Reboot firewall and check queues
vmstat -i

not working for me, 2.5.0, maybe they are valid for 2.4.5 but I can't test on it.
if it's only for 2.4.5 it will become old as soon as 2.5.0 is released
sysctl: unknown oid 'hw.vmx.txnqueue'
I think the new oid, following your example, are
dev.vmx.0.iflib.override_ntxds=2048,2048
dev.vmx.0.iflib.override_nrxds=2048,2048
dev.vmx.0.iflib.override_ntxqs=8
dev.vmx.0.iflib.override_nrxqs=8
[2.5.0-DEVELOPMENT][root@pfSense.kiokoman.home]/boot: sysctl -a | grep override
dev.vmx.0.iflib.override_nrxds: 0,0,0
dev.vmx.0.iflib.override_ntxds: 0,0
dev.vmx.0.iflib.override_qs_enable: 0
dev.vmx.0.iflib.override_nrxqs: 0
dev.vmx.0.iflib.override_ntxqs: 0

I will check on 2.5. Though reading this:
https://bugs.freebsd.org/bugzilla/show_bug.cgi?id=237166
If it has changed, the new values should be:
dev.vmx.0.iflib.override_ntxds="0,2048"
dev.vmx.0.iflib.override_nrxds="0,2048,0"
Edit: I tested on pfSense 2.5/ESXi 6.7 with the following in /boot/loader.conf.local
hw.pci.honor_msi_blacklist="0"
hw.vmx.txnqueue="4"
hw.vmx.rxnqueue="4"
hw.vmx.txndesc="4096"
hw.vmx.rxndesc="2048"
net.link.ifqmaxlen="8192"
I was able to see multiple queues. I don't believe these are supposed to show up in sysctl.
