Ooops, sorry for the unlisting, I was trying to move this to the Arm Category.
If you decide to buy a larger uSD card, I would suggest something like this.
- Designed specifically for video monitoring cameras (dash cams, surveillance & security cams, CCTV, body cams, etc.)
- Up to 43,800 hours of 4K and Full HD (1080p) recording and playback
- Reliability Built to Last – Water-proof, Shock-proof, Temperature-proof, X-ray-proof, Magnetic-proof
- Transfer speeds up to 100MB/s
This uSD is available in 32 GB, 64 GB, and 128 GB.
I have a RPi 4b with 4 GB RAM, a Rpi 4b with 8 GB RAM, and a RPi 400.
That said, I agree with @vlkon except I would go a step farther and say NOT to get the RPi 4b with 8GB RAM. I think the RPi 4b with 4 GB RAM would be the way to go for this usage. The RPi 4b with 8 GB of RAM has it’s own set of problems, especially if you decide to install the aarch64 (64 Bit ) OS system. A RPi 4b (and 400) can run either a 32 Bit OS (armv7h) or a 64 Bit OS (aarch64). The last time I checked, Raspbery Pi OS was only available in 32 Bit. Arch is available in either 32 Bit or 64 Bit.

EDIT:
Here is the work around for a 64 Bit OS on a RPi 4b 8GB Ram OR Rpi 400 mentioned above.

EDIT #2
Here is the Arch Linux Arm web site.
Click on packages and view the various OS versions. arm - armv6h - armv7h - aarch64
arm is for very old ARM devices
armv6h is for Raspberry Pi original
armv7h is for Raspberry PI 2
Raspberry PI 3 and 4 can both run both armv7h and aarch64
aarch64 is also occasionally reffed to as armv8 and is the only 64 Bit system
