Hard Disk Memory for Adobe CC

Apple no longer sells the MacBook. You currently have a choice between a MacBook Air or a MacBook Pro. For the apps you are proposing to use, I would suggest that you get the latter.

... and in that case, you will want it pretty much maxed out for both RAM and SSD storage space. The new 2019 16" MacBook Pro has both RAM and SSD flash memory soldered to the logic board ... so they are not upgradeable. When ordering, get at least 16 GB of RAM and 1 TB of SSD storage. With this model you can go up to 64 GB of RAM & 8 TB of storage ... if price is no option, as you are talking just under $5,900.00 (US)

If you have a limited budget, you could get by with a slightly smaller SSD, and then, augment it with an external drive. You can also consider getting a refurbished Mac that is slightly older. The 2019 13" MBP with 16 GB of RAM & a 256 GB SSD is around $1700 (US).

Each of those apps you listed have both minimum and recommended storage requirements that you can compare to see if there will be enough space on the internal drive. Don't forget to include additional space for future growth.

I would suggest you go for MacBook Pro. For using all these applications you need maxed out storage. So go for a version that gives you huge SSD and RAM powerful enough to handle the applications.

I would suggest you buy the MacBook Pro with atleast 16 GB RAM and SSD corresponding to it.

You're mixing and confusing memory with disc space.

The more the better, but MacBook isn't the best, also... the less RAM Memory you have the more SSD Virtual Memory you'll need.

How much space the OS takes is variable, but 20 GB would be minimal tending to much much more... 132.53 GB on my 10.13.6 System.
