I think the "Use surviving particles for ever slower calculations" is probably the most likely solution, assuming an empty universe/ heat death scenario. It was shown, I believe, that based on the expected rate of the expansion of the univese, a thinking being could have an subjectively infinite long period of time that way.

The converse is also possible; in a "big crunch" scenario, you would have a finite period of time, but the amount of energy available in any given volume of space would increase at an accelerating rate and approach infinity, so a being would (in theory) be able to think more and more quickly as the amount of energy available increases, and you could also experience an infinite amount of subjective time within an objectively finite time period.

(Of course, a "big crunch" seems very unlikely now, based on what we know of dark energy.)

Currently it's pretty commonly believed that the end state of the universe is decayed particles moving away from every other particle at faster than the speed of light, therefore existing in an eternal and inescapable void. If you only have one particle you can't do calculations.

That's one possibility. It depends what the value of dark energy is, which isn't yet known.
