They're the same thing. One is self-serving as an attack on others. The other is self-serving as an invincible excuse against any criticism.
"Inherently evil" races--races that have the capacity to make moral choices, but inherently always make evil ones--are a problem for both the racism reasons (isn't it just dandy that they're coded with stereotypical Asian, African, or Middle Eastern characteristics? Good gosh golly, so unfortunate that!) and for the simple fact that they crush any actual moral understanding that could be learned from the text.
If you do something like Oofta's "essentially bio-androids that are physically animated by the Dark Lord's will and cease functioning the instant that will is removed for any reason," that's substantially better, because (a) that isn't actually a race anymore, it's an organic machine incapable of making choices of any kind, moral or otherwise, and (b) being machines, they were intentionally designed by someone, and thus we can actually use this as a useful commentary against racism by noting that making your bio-androids racist caricatures is pretty evil in its own right, separate from what evil you happen to work with those bio-androids.
I guess in that sense, "inherently good race" is actually worse than "inherently evil race." Because the former invites the extreme temptation to have these "inherently good" beings be seen as Just Better versions of mortals. There's a twisted aspirational element to that. And, of course, it's extremely convenient for use in justifying all sorts of atrocities and horrors: "Well it can't be evil. The always-good angels told us to do it. It has to serve good, no matter how hard it is for us to understand."
Really? There's at least two distinct places where you exactly contradict that:
How can they be PCs if they aren't thinking, feeling people with individual personalities, desires, and motives? Isn't that a fundamental part of being a PC, in all but the most extreme pawn-stance game?
Here you just straight-up say nonsense. It's not possible to have "sapient....individuals with personalities" that don't have free will. Further, if it's literally not possible for them to not choose to do horrible, disgusting, dangerous, corruptive things, then they cannot be evil. You have to be able to choose to do evil or good. Otherwise you just...aren't either. You aren't even on the alignment grid at all, which is why we have Unaligned. How is it even remotely possible to be "sapient" and be "individuals with personalities" and "make choices" and yet not have free will?
This is why all relevant celestials in my home game (mostly angels, demons, and devils, though couatls have also been shown to fall into this category) have a reason why they're "Always <Alignment.>" They fought in the War in Heaven. They waged an infinitely-long war for one of the three ultimate factions: the loyal Servants who upheld the will and the divine plan of the One, the loyal-but-disobedient devils who wanted to uphold the divine plan but disobeyed the One's command to never use coercion on mortals, and the twice-fallen demons who came to revel in the destruction/death/pain/emotionality and thus sowed chaos for its own sake. Devils believe they "won" the right to play out their philosophy, while the Servants believe the devils were punished to be bound by the very rules they hoped to apply to mortals. Demons believe they "won" the right to rapaciously sate their eternal, unquenchable desires on the world, so long as they can draw mortals into similar debauchery, while the Servants and devils see them as punished to be enslaved to those desires for all of eternity.
