Key factors that I need for Electronic Engineering:
Color in Red is must, Color in Green is optional
RMS Hz, % for testing some servos, pre-defined signals
At least 50000 counts, 60000 counts is great for testing voltages around 5V
dbm (for testing some RF signals. Usually I can use an oscilloscope which has FFT with a 50 ohm attenuator to do this test or a VNA but it would be great if you can have it in a multimeter.

)
mV and mAVFD (variable frequency drive) Optional. Can be used for motors and robotics tunning
USB to PC Optional. Sometimes it's very useful
Previously I had a Uni-T 61E+ but its mA position showed incorrect 50% value of the correct value using A position which is ridiculous for serious EE.

Candidates:
1. Brymen BM869s ( 500000 counts in DC mode, dbm, VFD) ( a youtube review:
https://youtu.be/aSrq3UJt4qU?si=wh4bY9do9DfDPpPa)
2. Brymen BM789 (60000 counts, dbm)
3. Brymen BM786 (60000 counts, no dbm)
4. Fluke 289 (50000 counts, it has 50 ohm position, dbm, ) (too expensive, won't buy)
5. UT181A ( 60000 counts, dbm (4ohm-1200ohm) and dbv claimed to be same accurate as Fluke 289 but at 50% price)
6. Rigol DM858 or DM858E (More powerful. Can be powered by a power bank. DM858E is at almost the same price of BM869s but it's a Benchtop Multimeter. Manual here

What do you suggest, and why?
Appreciate your comments!
