The Ryzen 5000 series should be a good choice for such an application, they’re still quite powerful CPUs. You should just make sure that you get the notebook/APU variant of the CPUs (e.g. 5600G or 5600U) and not the desktop variant (e.g. 5600 or 5600X). The desktop variant has significantly higher idle power consumption (see e.g. www.reddit.com/r/…/nas_idle_power_usage/, they report 50+W in idle, while my 8500G system idles at 17W). The one you linked should be fine.
