I would say there is no perfect neither totally wrong partitioning. No magic scheme but partitioning fitting - or not what your needs and goal.
Which mean that you have to define first what you want to achieve.
So I don't have any magic but can tell you what I did for my own installation and why.
/ on SSD
swap on SSD to but I've plenty of memory thus swap is not really used.
/var on RAID 1 (2*HDD) (ext4)
/home on RAID 1 (ext4)
/var/log on dedicated HDD, single spindle, etx2 (I can't see the benefit of ext4 here)
No done on my side but however perhaps nice to have depending on how you deploy, /srv/www could benefit from RAID 1 (I'm not using it as all my data is on /var/www)
