Yes as you have found - you can only enable the higher quality Software upscalers like Lanczsos3-optimised when CPU software decoding.
And to do that Mediacodec Hardware decoding has to be turned OFF. But that is a hassle when all other content does not Hardware decode.
Fear not hope is in sight, because after a LOT of hassling Android Kodi devs are finally considering implementing mpeg2, mpeg4 and h264 user configurable SW/HW decoding for Android. Which is what SPMC 16.x had included years ago. AMLogic LibreELEC users had this as well.
Have a read of this thread and install the .apk

Then play around setting the "HD and Up" options. 1080p content will still hardware decode that way. (Leave Mediacodec acceleration Enabled)
Make sure you also leave - Enable HD scalers for scaling above as default > 20%
The higher that figure is will dictate if the higher quality scaling options show up in On Screen > Video settings or not - when CPU software decoding.
When this high quality scaling works it works well to sharpen picture outputs for old SD only video content.
And with the SW/HW video acceleration user settings options added - it's "Set and Forget" - the way is should be
