Lighting Design and Driver Selection - check my work

I ordered (3) LED strip lights that will have two separate circuits on them. Some of the circuit details are below:
Circuit 1:
96 Samsung 301B in 5700k (per strip)
Operating Voltage - 23.2 – 25.4 Vdc
Operating Current - 2400ma (per strip)
Max Current - 2800ma (per strip)
Circuit 2:
48 Samsung 301B in 3000k, 2 Osram 660nm deep red, 1 730 nm far red
Operating Voltage - 23.2 – 25.4 Vdc
Operating Current - 1200mA (per strip)
Max Current - 1400mA (per strip)

I would like to run these on separate drivers so that I can digitally control them separately through Home Assistant. I would like to write some automation that will do red fades at lights on/off and be able to generally control them digitally. SolStrips recommends their strips are wired in parallel.
My math is as follows:
Circuit 1 - 2400*3 = 7.2A operating current with a max of 2800*3 = 8.4A
Circuit 2 - 1200*3 = 3.6A operating current with a max of 1400*3 = 4.2A
Circuit 1:
Looking at the Meanwell HLG series, I could go with an HLG-185H-24AB and run at the "operating" current listed (note, SolStrip says you can max them out, but efficiencies go down beyond the rated operating current). I could step up and go to the next level higher of the HLG-240H-24AB, but I'd have to make sure to set the upper limit on the pot.
Circuit 2:
Same as above, but would go with the HLG-120H-24AB
Are these the right drivers? Should I go with the higher rated driver for circuit 1 and dial it back? Am I missing another series of driver that might be better?
Lasltly, as a newb to Home Assistant, but someone who has created a single automation with a pump timer (thanks @LEDG ), what hardware should I be looking at to control the drivers through home assistant? Need some sort of digital potentiometer that I can connect to my RPi. Thanks for the help.
