We did the St. Johns in 2018, no problems in our 5' draft, it gets skinny on some of the lakes, but really a non-issue. There are plenty of places to provision, lots of Old Florida charm, we had no problem with provisioning, most of the larger towns you can find an Uber. We carry 900 gal of fuel, so that's not ever a concern. There are places along the route to fuel. A number of public free docks, no power most no water, but great stopovers. Hontoon State Park is really delightful. All very laid back. There's a large marina at Sanford, lots of cruisers make it a winter camp out destination. Delightful town. St John's cruise should be a must on every cruiser's itinerary list. We thoroughly enjoyed the trip.
