How to partition is a judgement call. Probably best to do a default install and see what that creates first. It is less than 15 minutes of your time. Which file system(s) you use can matter greatly as well. Some include volume management and more advanced capabilities which are both more complex and more flexible.
Only you can decide is the extra complexity that any specific partition scheme provides is worth the extra hassle.
Over the decades, people have posted their disk layouts in these forums many times. Some with explanations. Have you looked at those?
To help, use this command to see the different layouts.
Code:
lsblk -e 7 -o name,type,fstype,size,FSAVAIL,FSUSE%,label,mountpoint
That will work with most file systems, but it does misrepresent storage in some volume managers like ZFS and BTRFS. Still, it is the best command I know to see an overview.
I should say that I've never, not once, had my initial system layout be perfect for more than a year. For this reason, I switched to using LVM because it doesn't require me to be perfect on the initial layout. But it does add complexity for that extra flexibility.
Good luck.
