I'm not sure if Scarlatti is early enough to be applicable to this thread, but since you brought him up, I've been going through a fair bit of the Scarlatti-on-piano (and some of the harpsichord, but there's more piano stuff) catalogue and have a number of recommendations.
In first place I'd put Aline Zylberajch's disc on Ambronay, on a Cristofori instrument from the 1740s. Maybe even more for the instrument than the interpreter, but both are very fine. There is a bit more Scarlatti on fortepiano but less than one might imagine (one disc by Linda Nicholson and one by David Schrader, neither of which has made as much of an impression on me, and a few of the sonatas in the Belder integral).
Among the "classic" piano recordings alongside Horowitz I'd put Maria Tipo, the "Neapolitan Horowitz", whose Scarlatti I prefer to Horowitz's actually, Marcelle Meyer, and Christian Zacharias's EMI recordings—would consider all three essential for any Scarlatti enthusiast. Anne Quéffelec is also good, although better on Mirare than Erato.
From the Naxos series the only pianists I've liked have been Benjamin Frith (vol. 5), Evgeny Zarafiants (vol. 6), Soyeon Kate Lee (vols. 8 and 21), Goran Filipec (vol. 19) and a standalone disc by Balázs Szokolay. I may give the remaining volumes more detailed listens at some point though, as this was based on sampling of fairly brief snippets.
Nikolai Demidenko, Sergei Babayan and Michelangelo Carbonara also have very good individual albums which may or may not be easy to find. Mikhail Pletnev, Claire Huangci and Yevgeny Sudbin are a bit weird but committed to whatever they're doing, so that may or may not be of interest.
