2010 Ranger 4cyl will be the 2.3l DOHC Duratec engine, Mazda L engine, Read here:
https://en.wikipedia.org/wiki/Mazda_L_engine#2.3L_(L3-VE,L3-NS,L3-DE)
It will have the 5R44E 5-speed automatic, or the M5OD-R1 5-speed manual as far as transmission options
2002-2012 Rangers used the 2.3l Duratec engine
But......in 2001 Ford dropped the 2.5l SOHC Lima engines mid-model year and started installing the 2.3l Duratec, so there are some 2001 models with "same engine" as yours.
The "2001" to 2003 2.3ls have electric thermostat and Intake Manifold Runner Control(IMRC), both were bad ideas and dropped in 2004 model year.
1997 and earlier Rangers had the 2.3l SOHC Lima engines, so Google search of "Ranger 2.3l" will get mixed results
1998 and up 2WD Rangers used coil springs up front, but some EDGE models used torsion bars
Lowering the truck down ideas here:

I wouldn't count on "pre-wired" cruise, look at 3rd party cruise control, or find a wrecked Ranger with matching steering wheel with cruise buttons and clock spring, then start pulling out the parts and wiring
Probably no on automatic headlights, but could have DRL(daylight running lights), i.e. head lights are on when truck is
