I think Fedora aligns partitions to 1MiB boundaries and disables atime (with relatime),
both things are good for SSD drives.

Using tmpfs for /tmp is also ok.

I've been using SSD drives for a couple of years, and in my opinion
concerns about logs and swap are exaggerated.

And having swap on SSD is a GREAT thing if you use hibernation. :-)
