1) I haven't been able to afford a fretless for a few years. I had to sell all of my basses except for one, which was a fretted one my wife bought me. But at that time I played fretless 80% of the time.
2) I preferred fully unlined but with side dots every few frets (1, 3, 5, 7, 9, 12, 15, etc)
3) unlined
4) I would seriously look at other/custom options. Worst case scenario, I would lacquer the board black (to make it look unlined) and would finish it with CA glue or something to seal the paint.
5) started lined, and found myself staring at the lines to see if I was on pitch or not. I didn't trust my ears. I ended feeling very restricted and was not having an enjoyable experience. I also found out that the fretlines were never all 100.0% accurate at the same time (due to neck relief and other factors) and realized staring at the neck/lines was a horrible thing to do and that I had to learn to trust my ears, but I simply couldn't stop looking. I decided to buy an unlined neck and see what happened. I had no choice but to use and trust my ears. After only a few days, the weight of insecurity and the restiveness of staring at the lines was gone and it was great. Lined fretless? Never again.
