Nrchy,
The arms you're considering are all low "maintenance". Once set up there's little to do. The Graham 2.2 does require damping fluid and getting it right is critical. But once you've got it things should remain stable, at least until you change cartridges. The TriPlanar and some SME IV's have a damping trough, but unlike the Graham you don't have to use it. We haven't found it helpful on our TriPlanar. I cleaned the oil out months ago and the trough just sits there empty.
Whether you adjust arm height (or anything else) for each record has little to do with your tonearm. It has much to do with your cartridge, your ears and your listening preferences.
Cartridges with micro-ridge or line contact styli (including ZYX) are more sensitive to SRA than cartridges with elliptical styli, which in turn are more sensitive than cartridges with conical styli. If you truly want to set-and-forget then choose a Grado or a Denon 103. You won't need to adjust very much because they won't respond to the adjustments anyway. Of course you won't hear all the music either. That's the tradeoff.
Getting the very best sound from vinyl does require working at it. Anyone who says otherwise has a limited system or limited ears. If you're happy with and relaxed about a notch or two less than top performance that's perfectly fine of course. You can save yourself a lot of work, and a lot of money too.
