I used the guide from raspibolt.org to set up electrs with sparrow a few weeks ago. It's my first node. Blockchain took ~4 days and electrs db seemed like it was significantly shorter...I think 18 hours or so.

Even after NVK and the Start9 dev on last Bitcoin.review pod spoke negatively about using RPi for a node, I just pre-ordered the RPi 5 🤦 Hopefully the increased power to USB bus will eliminate *potential issues with NVMe storage 🤞

Some day I'll grow up and get a real server.
