I was hoping for information to be passed by tmpfile or environment variables..

That is what I have done in the past...leveraging a 'feature' in the installer :)

Normal install from ISO up to 'partitioning'
Select 'Finished partitioning' without doing anything, to 'base install' which complains and stops

Open up second terminal
Create /target directory and mount storage
Switch back to installation terminal
Select 'go back'
Select 'go back'
Continue with 'base install'
Base install would then proceed without partitioning using whatever it found in /target

Unfortunately I cannot get a UEFI secure boot install on NVMe to work with that method...

Nothing unusual, a very straight forward layout for '/' I have used for donkeys (10 years+)
F2FS -> LVM -> LUKS -> Metal (that last one is actually silicon ;)

F2FS cos almost everything I do now is on SDHC, NAND, NVMe,...I typically get 3<>4.5 times real world throughput using F2FS over EXT4. Note this may be down to cacheing, sheduling differences not just filesystem, 512MB total SDRAM doesn't go very far. A Raspberry Pi will fly when using F2FS in preference to EXT4 on a cheap SDHC.
LVM for dynamic partitioning, resizing, etc.
LUKS cannot dynamic resize etc .. goes at the bottom, full disk (full 2nd partition when UEFI) encryption to avoid data leakage at rest.
