Recently rewatched Dragon Half; how the hell did they get that cast!? Still the best Beethoven cover performed by a Sailor Moon VA that I'm aware of, too.
Other than Frieren, it has been annoying that most of the Fantasy Genre Anime have been Isekai.
The isekai boom does finally seem to be waning, but it's definitely a slow decline.
The Ambition of Oda Nobuna is probably the most non-RPG isekai out there (and a very good anime all around), but as you say it was a single season show.
Konosuba S3 been delivering as well as Date A Live S5; been watching "The New Gate" and am enjoying it; similar to SAO and Log Horizon but a more unique story
