First of all: thank you for this topic, it was very clear and very helpful.

I am short with time (and lazy too), so I've installed TryNinja's plugin (thank you!) into my Electrum.
I've added into bitcoin.conf the lines from @Cricktor post and I've added the only clearnet node from @Pmalek post (I'd feel better if the list would be bigger).
I've restarted by bitcoind and my Fulcrum and I've made a tx with 0.3 sat/vbyte as fee. It's already confirmed too.

All the info is there, and it works!


A small suggestion would be to maybe centralize all this into the first post so the ones even lazier than me (who also have local ElectrumX) can use it.
