Intro from Louisiana and suspension help

Hello to everyone! Just wanted to introduce myself and see if anyone has recommendations for suspension. I got this Vivi ebike off of Facebook Marketplaces for a steal. Had it for about a year now and it's been amazing. So far I've added the light bar, mirrors, 140db horn, 3 camera system, Ibera rack system with bags, suspension seat post, pedals, Schwalbe tires, handlebar extender with on board charging, 4 piston hydraulic disc brakes with larger rotors, adjustable rear suspension with lockout, and for the long runs, a trailer. It's pretty comfortable as is with the exception of the front suspension. It's the stock forks, and any decent bump they bottom out which tends to get painful on long rides. I'd like to do something other than just replacing with factory forks from the manufacturer, preferably adjustable with lockout. With it being a folding ebike, the steerer tube is at 145mm tall and threaded. I've not been able to find a fork like I am looking for in those dimensions so I am looking at the possibility of switching over to threadless, but have never done this on a regular bike much less on a folding ebike. Would anyone have tips, guidance or suggestions that would help me accomplish this? It's my main mode of transportation after a couple brain surgeries so comfort is everything. Any help is appreciated!

I have changed forks from threaded to threadless. I probably didn't need to do it, but I also put in a new headset, which meant knocking out the top and bottom cups, followed by pressing in the new cups in the headset.

Well, the old cups are easy to knock out with a screwdriver and hammer. The new ones can be squeezed in with a length of threaded rod stock, nuts, and washers,

I was concerned that the old cups might not have worked with the new headset, but I was probably just being overcautious. At the time, the headset was only 12 dollars.

Yes, finding threaded forks with the right length steer tube can be very hard. If you find a long enough tube, the threads may not be long enough, and they are very difficult to cut unless you use an expensive hardened die.

After changing to threadless, you now have to find a sturdy threadless folding steerer. That can be hard to find too. Many of the folding steerer assemblies, threaded or threadless, seemed flimsy to me.
