You don't mention the video editor software you use, and that may be relevant in choosing the best machine for the job.
I use Davinci Resolve V20 and my bog standard MacMini M1 does everything I ask of it. One caveat, I rarely use Fusion (motion graphics), the most demanding part of the software, and I know this machine will not be up to the task if I push it in that direction. My previous high spec Intel machine would sag if I threw any complex colour grading at it. The Mini M1 was a huge upgrade in function and rendering speed and continues to work well even though Resolve has become much more complex and power hungry.
I am about to upgrade within the next 6 months and have been watching a lot of YT videos showing the capability of the new M4 machines. Again, the lowest spec machine seems to smoke the competition, even those with much higher specs. nb. My concern and research has focused on Resolve, so another editor may be better served by something else.
Looking at specs and real world reviews of the current machines I "think" I have settled on an upgrade path(s).
Option 1: Go for the M4 Studio. Its higher Core and GPU count will allow me to take on much more intensive projects, including Fusion and likely last me another 8~10 years.
Option 2: Go for the standard M4 machine and a similarly spec M4 MacBook Air, allowing me to leave the Mini at home when I travel and still have a nice machine for all of my remote audio and most video editing tasks.
Pricing for option 2 will come in around the same as going with a MacBook Pro. I will leave it to you to confirm that, as pricing seems to differ depending on where in the world you live.
If I go for Option 1 I will keep my current M1 machine and use it as a backup/travel device. I take it out now in a Pelican 1500 case configured with a top lid mounted 18" USB-C monitor, the M1, mouse/keyboard, and a couple of 1TB portable SSDs. Going with a current M4 MacBook Air would be a considerable weight and size saving, so I am leaning in that direction.
Lots of options, and that is a good thing.
