at one point we were going with a 2TB ssd nvme. you've stated you're fine with 1TB (I too thought you would be ok with it at first) since your typical laptop usage involves a 500GB ssd.
so how much storage you'd be ok with typically depends on the games, apps and other work you do. that is something only you would be able to tell.
most motherboards we've considered have had multiple m2 slots so in the future if you need to expand your storage you should be able to easily purchase a drive and add it without having to change your existing drive.
likewise you are ok with a lower psu wattage when you went down from 850W psu to a 750W psu. so future proofing seems less of an issue for you.
so these are questions which you will be able to best answer, because you know your requirements best.
saw its review by Hardware Unboxed and reviewer said thermally it performs worse than Asrock B650M HDV M.2. I checked PRO RS as well, but apart from extra slots couldn't find any plus points over HDV.
there was a vrm thermal test video by hardware unboxed some time back, did someone point you towards it ?
the test was conducted on a ryzen 9 7950x coupled with a 360mm liquid cooler stress testing the system using cinebench.
if you follow the reviewer he specified they were less concerned with the temps and more concerned with whether the motherboard passed or failed.
temps were high for the msi board but technically it passed.
the ryzen 9 processor is a very high end cpu and in this test it was being pushed to its limits.
the default power draw during this test for the ryzen 9 processor would be close to 230W. higher power draw usually equals higher heat generation.
in contrast the ryzen 5 7600 you will be using will have a max power draw of about 90W.
most gamers typically go upto a ryzen 7 processor. ryzen 9 is considered overkill for gaming, its more for content creation, video editing, 3d modelling and the like.
its funny you mention hardware unboxed because one month after the vrm thermal test video they put out another video the b650 buying guide.
in that video they referred to this msi board as being one of the better boards at its price points. (check below)

this msi board is a competitor to the gigabyte b650 eagle ax which has came up once or twice in this thread.
per the reviewer both those boards should be fine for ryzen 5 and ryzen 7 processors but they would not recommend the same for ryzen 9 processors.
the reviewer acknowledged that the gigabyte board had better vrm thermals but he leaned towards the msi board due its stronger feature set.
this combined with the fact that the msi board is selling for less in the indian market led me to recommend this board to you.
i also found this convo about a user looking to upgrade to a 9800x3d (which is the fastest gaming cpu currently) from a 7600. as you've mentioned you'll not be overclocking so at stock settings this msi board should be able to handle the 9800x3d.

maybe consider reaching out directly to hardware unboxed with your requirements, future plans and ask whether this motherboard will meet them ?

oh not much plus points?
so when you compared this msi board with the asrock hdv m.2 , you did not say notice the presence of the word wifi in the name msi pro b650s wifi as opposed to the lack of the word wifi in the name asrock b650m hdv m.2 ?
the msi board comes with inbuilt wifi, if thats not a requirement for you or if you are otherwise uncertain about the msi board after seeing the vrm thermal test video, consider the asrock. in the future if you need wifi functionality you'll need to buy a wifi card separately and put that in.
