The conventional wisdom seems to favor golf cart batteries for a number of reasons, among them being capacity/weight, ease of handling, flexibility, etc. What am I missing?

For a couple of reasons:
1. Simplicity of design and purchasing.
2. To have 12V you have to have 2 of the 6V and if you run them in parallel to increase amp hours achievable then that is four of them when only two of 12V would do. This means that at any given time if 1 fails - it immediately effects all other batteries rigged to ..that is 3 other batteries and trying to isolate whichever one is dead....kinda painful unless you enjoy doing that troubleshooting thing
3. The saving weight / additional amps is a myth... (see #4) the additional battery cables will often offset what supposed minimal gains you get from x more amp hours (but then most try to buy the cheapest not necessarily fitting to what ones boat requires)....
4. More corrosion of cables as there will be more cabling involved. and cables are not cheap often offsetting savings of purchasing two 6V versus a single 12V battery
5. Batteries are the core of the electrical system of a boat typically. The least amount of parts to make the system work saves in maintenance and troubleshooting time spent...
That is just the short list
