You've asked questions which are largely down to taste so you will get a lot of different answers. I would use "manual layout" in the installer to ensure I got exactly what I wanted. I would use whatever filesystems I wanted and not care about SSD writes unless it's an ancient SSD or a truly exceptional use case. For most uses /tmp is best left as a tmpfs (memory-backed) and /opt starts off empty. If you think you're going to use /opt then you must have some idea what you're going to put into it. I would put a 1G or so swap partition on HDD and then dedicate whole rest of the HDD to either btrfs or to LVM, in both cases for the purposes of volume management. That way if your initial guesses for sizing are incorrect you can easily change them and/or switch things into btrfs subvolumes or LVM logical volumes later on. But to be honest, SSD is life changing compared to HDD so I'd want to put everything on SSD as long as it fits. I am a big lover of redundancy so the lack of matched pairs of storage worries me, but assuming that can't be changed I think I would use say the first 5GiB of SSD for / and then the rest as either btrfs or LVM again for volume management. I'd then create subvolumes or logical volumes for /home and /var and initially have them on the SSD for speed. I'd move them into the btrfs/LVM on the HDD only if you began to run out of SSD space.
