For the last week I have been doing a lot of research about this topic since I experienced the same issue.
My Setup is a HP Thinclient 730 with a Realtek 4 port 2.5gb card (RTL8125).
What I did was the following:
- I disabled all functionalities to make sure my firewall was clean
- Monitored what what traffic was blocked to see if there was any patern
- Tried all the tips and advises from other posts (non if it worked)
- Allow listed all Google Services in the firewall by creating an Alias for the following list

But the strange thing was I didn't see any traffic of google being dropped, while still Youtube was performing bad and the playstore took ages to download a simple app. Since somebody mentioned that his fix was replacing the Realtek card for an Intel I went to see if Realtek maybe had new FreeBSD drivers, but the plugin package provided by OPNsense has the latest version.
So I was all out of options and ordered an Intel I225-V this week, it arrived today and guess what all my problems are over. Even have a feeling everything runs much more stable now.
In case you are interested I ordered this card:

And returned this card:
