IMO pis are super convenient and reliable minus the power supply and SD card. So for power make sure you are using an official power supply, not just a spare phone charger. For storage, you can boot the new ones from a few different media, like a thumb drive (https://www.tomshardware.com/how-to/boot-raspberry-pi-4-usb) . Get a little ethernet cable and attach it to your router for best performance.
