I am sorry to hear that Sam has FIV. Many of these cats have sores in their mouths, called gingivitis, that make eating difficult. Pain medication such as Onsior or buprenorphine, can be helpful. These are by prescription, there are no safe over the counter pain medications for cats.
A picky appetite could be a sign that the infection is making him sick internally. Even though he acts hungry, appetite stimulants such as mirtazapine might make him eat better.If I could, I would take his temperature (normal rectal temperature is between 101 and 102), check his mouth, feel his lymph nodes and internal organs for signs of the FIV causing problems. FIV positive cats can live for years, but eventually become immune suppressed to the point of developing secondary infections that can be serious.Please let me know if this is helpful and what other questions you have.
I hope you were able to see my responses. Please let me know if this was helpful and if I can answer anything else.
