If you're willing to be more or less tethered to a computer, you could severe your wishes. You could "invest" in the keyboard with the keybed that suits you most (number of keys, key mechanism, aftertouch), accept the type of synthesizer (workstation, arranger, mere synthesizer, mere MIDI controller), and use devices in software for the rest.
For comparison, this is the part-story behind my four keyboards mentioned above:
I did not at all plan to buy keyboards after a Korg MicroKey 2 Air and later also a Worlde P88 keyboard controller, both in 2021.
The release of the Fantom-0 series made me think that I could "easily" transfer the patterns of my 1990 songs (recorded in a file format that pre-dates General MIDI) to that Fantom, tweak them, and find the fitting sounds for them. (In 1990 I had a Roland U-20 synthesizer with a far from all-round sound set, plus a few expansion cards. I resorted to Pizzicato Violin for a banjo sound, among others.) - I still consider the Fantom-08 a crucial factor to realizing my plans, even though I haven't touched it in nearly six months now. I plan to use it mainly for emulating "traditional" instruments (including electric guitars).
By the way, I seem to remember that JunoX was included in the "Zenology Pro Analog Icons" expansion bundle that I bought at RolandCloud for my Fantom. (I did spend some time looking that up, but I failed.)
The Hydrasynth Deluxe was the result of a thread (here or over on gearspace.com). I have never been into synthesizing beyond physical modeling (Yamaha speak) or virtual acoustics (Roland speak) but I imagined that this would be a great device for playing with waveforms. (Please don't insert a debate here about "the best synths for playing with waveforms".)
I had finally purchased the most expensive edition of NI Komplete, and I considered the Komplete Kontrol controller a proper way to manage its components, as well as compatible software from other developers (notably EastWest).
Finally, the Thomann AK-X1100 started as a quest for a Korg Pa4x Oriental. (I don't feel like checking if it was this very thread that caused it.) I had to give up on "Oriental", but I thought that it might be worthwhile to have an arranger keyboard with integrated loudspeakers after all. Just after ordering, I discovered the Oriental sibling of my device: the "Dante Zen" by Medeli. (Oriental editions of arranger keyboard feature an extra group of buttons associated with scales, and sounds and styles associated with music from Türkiye, Iran and surroundings.)
My recording project doesn't involve oriental songs, but I do have a song in Greek 7/8 measure. (I suspect the American oldie "Misirlou" to have been stretched from such a 7/8 to a rumba.)
So, I've ended up with four new keyboards. In my view (not yet opinion) they represent different approaches to what keyboards could be. - And now that I have differing MIDI-keyboards, I can turn my attention (once more) to the sounds I want. I'm very pleased with my Ferrofish B4000+, a drawbar-organ module. It represents my love of certain songs by Procol Harum, but those drawbars with numbers should also amount to another way to playing with waveforms.
