You'll like it. It gives one the full Monty on limited access highways: Lane switching on its own (with or without warnings.. I like the warnings, which are audible/tactile), will go from an off-ramp on one interstate to another interstate. On long trips, it's great. My SO got her 2021 MY without EAP; we rented it for a trip to Boston, then decided to buy it permanently. It actually makes one's trips on interstates safer; it won't hit somebody in one's blind spot, period.I ordered it with Enhanced Autopilot and am really looking forward to using it. I've very comfortable with cruise control systems and this, as you say, will be fun!
One does have to keep one's hands on the steering wheel and apply changing torque and must keep eyes looking out the windshield. My approach is to supervise and look for Maniacs, full time.
One can run EAP on local roads, to some extent, but it's not really designed to do that. I think EAP will come to a halt at any light, green or red, unless one confirms with a boink on the shift lever. Once stopped, one has to "boink" again to get started when the light turns green. The interesting exception is if one is in TACC/LK and actively following the car in front of one, if that car goes through a light, the car will, too. FSD will actually do city streets, but it's like a somewhat brain-dead student driver: It will occasionally do Really Stupid Things, sometimes not all the time, and it doesn't learn, outside of FSD software point releases and/or map updates.. I think you'll get a one-month trial of the software when you get the car.
If you decide to try the trial, you'll have to acknowledge Tesla's absolutely correct dire warnings about Paying Attention, including the phrase, "The car will do the wrong thing at the worst time." (Their words, that's a quote.) Having said that, it's pretty amazing technology. When it works. Which, these days, is most, but not all the time.
