It this point, supporting Raspberry Pi4 should be expected of a broadly available system like TrueNAS. There are other, good, 64bit arm boards, but the RPi does dominate the market and it is 'easy' to build a complete system around it. This would easily fit into the space recommendations in this article.

TrueNAS requires a minimum 16GB RAM, though it can run on 8GB in a somewhat limited mode.

I have a specialized FreeBSD variant that works on ARM, and runs at least as a VM on ESXi ARM Fling (I haven't tried bare Pi lately). I can say that there's some differences between AMD64 and ARM64 especially around bootloader and device support, but it is probably not an insurmountable challenge to get TrueNAS running on ARM.

However, "should be expected" would appear to misunderstand the nature of TrueNAS. The developers are not actually developing this so that it will run on any platform ever. It is intended for the TrueNAS Enterprise systems that iXsystems sells (which in turn fund development), a very specific platform. However, unlike Apple and MacOS which is locked to Apple platforms, iXsystems allows TrueNAS to be used by anybody on random platforms, even though it is really targeted at a specific hardware platform. They'd probably accept patches to make it more compatible with ARM as long as it didn't interfere with AMD64.
