Rule of thumb: your preferred FS will be OK. Limiting write is not a goal in and of itself.

True for SSDs; if you're using COTS SD cards (think RPi), it might be still a concern.

I managed to get plenty of useful life from an old, failing SD card by only loading (R/O) the bootloader, kernel and initramfs, and never touching it beyond initramfs (mount a USB drive as /). Similarly for an ancient PATA (!) SSD in a netbook: grub+kernel+initramfs, and nothing else; saves me from a USB stick out the side.
