If not, is there a way to "Disconnecting Bluetooth Accessories Not Until Tomorrow", but indefinitely, from the Control Panel? Because I want to keep bluetooth solely for Find My, and I don't want to keep disconnecting bluetooth each morning.
To be more specific, I'm talking about the Find My Network feature, the global network of bluetooth-enabled Apple devices (which is crucial when your device doesn't have a connection to the internet).
No, you will have to accept my knowledge of communications technologies acquired over the past 50 years (I invented a predecessor to Wi-Fi, that never went anywhere because Motorola was the 800 pound gorilla in the field). You are free to research it if you want to; there are hundreds of pages of the Bluetooth specification that discuss how it works and its power consumption. The Wikipedia article for Bluetooth include information on power consumption. But the summary: A Bluetooth connection to a listening device typically uses 10 mw. If there are no Bluetooth connections the Bluetooth circuit listens for devices every few seconds, but that is just a receiver and uses less than 1 mw average. As your battery is typically around 3,200 mw-hours, if there are no active Bluetooth connections and nothing else on the phone was using power then BT would drain the battery in about 320 hours, or 2 weeks. The Find My network uses uses the listening feature, so it also only uses 1 mw.

Bluetooth uses no power when there are no devices actively connected. Likewise for Wi-Fi.

Bluetooth has nothing to do with find my iphone.
Find My Network won’t work with Bluetooth off. However, other Find My features will still work. Why are you turning off Bluetooth? There is no reason to.
I meant Find My Network, sorry. i.e. when you don't have internet.
Are you able to provide an official reference about this?
Does Find My work on iPhone when Bluetooth is off from settings?
