The OP is a new member and like so many new folks asking their first questions get scared off or put off.
I'm posting all this for the OP but If I was ordering a new F150 I would get the "MAX TOW" option which Ford says is:
Available on XL, XLT, LARIAT, King Ranch®, and Platinum models.

Includes:
• 3.55 Electronic-locking rear-axle
• 4-pin/7-pin wiring harness
• 36 Gallon fuel tank
• Auxiliary transmission oil cooler
• Engine oil cooler
• Class IV trailer hitch receiver
• Pro Trailer Backup Assist with Tailgate LED
• Smart Trailer Tow Connector (standard on LARIAT and higher)
• Integrated Trailer Brake Controller
• Upgraded front stabilizer bar
• Upgraded rear bumper

Requires 3.5L EcoBoost® engine.
Does not include Trailer Tow Mirrors. Trailer Tow Mirrors are a standalone option and must be ordered separately.
Max GCWR/Max Tow achieved on SuperCrew® when equipped with 20-inch Wheels. This configuration will also come equipped with max springs, steering gear, and upgraded stabilizer bar.

Also the OP needs to make a decision on GVWR/RAWR packages as the F150 has many different selections..all can be had with the 3.5 ecoboost engine and the MAX TOW option but have different payloads depending on RAWR...some quite small. Package #2 may not be offered anymore.
We see so many new folks buy a F150 with the small 6700-6800 gvwr and tiny 3800 rawr with MAX TOW option thinking the truck can pull a 8k-10k trailer...'cause it says MAX TOW.

#1. 7850 gvwr...4800 rawr....2500 lb in the bed payloads.

#2. 7600 gvwr...4550 rawr... 2200 lb in the bed payloads

#3. 7050 gvwr...4050 rawr... 1800 lb in the bed payloads

#4. 6750 gvwr...3800 rawr...1500 lb in the bed payloads.

2020 fleet ford specs
This is for 2020 selections but will give you a idea of all the packages and specs on the F150 from Ford.

My point in all of this is that the difference in price between an F-150 set up to tow with eco boost engine and a F250 diesel is not $10,000.
As posted there are lots of packages and combinations. Max Payload , Max tow are a must have, towing mirrors are also prerequisite.
Comparing a base price eco boost F-150 to a base price F-250 does not tell the whole story.
The F-150 will require additional packages($$$) The F-250 is capable right out of the gate.
In the end the bigger chassis and brakes of the F-250 will make it a better tow vehicle.
Much in the same way the higher rear end will always deliver better towing performance. Multi speed transmissions tend to blur the issue but the higher ratio always wins when towing.
If your plan is to tow a large 8-10K GVW TT the 3/4 ton truck is the better option. This is a towing forum where the focus is on towing ability.
If your plan for the truck is for purposes other than towing
then all bets are off and the advice given becomes relative to the desire to have a fully capable tow vehicle.
