It depends on the brand and type. They usually settle in after 50 miles.

The vehicle owner’s manual for new vehicles often advise to avoid hard stops for the first 500 miles. I would do the same with new rotors and pads.
^^THIS^^
I don't think it would really take 500 miles, perhaps 100 or so, but just be a little more careful about slammin on the pedal for a little while (unless absolutely necessary) until the new parts get settled in, then you should be fine
Last year, I upgraded the rear brakes on my '11 with ceramic pads & slotted rotors, and it was a bit touchy for about 2 weeks, but the improvement in braking performance compared to standard/OEM replacement parts was like night & day, so I plan to do the same on the front when the time comes (probably this fall/winter)
???? please elaborate
How and Why to Bed Your Brakes
There’s one last step to replacing your brake pads, bedding your brakes. Make sure your brakes and rotors are warmed up and road-ready before you take off. J...

There ya go.
Thanks for the info. Mother in laws expy. She wants factory stuff. I personally like bendix Fleet lock metallic pads. I know your rotors don't last as long but it stops when you need it to. I don't know how metallic pads would play with the adaptive braking, hillstart assist, and the anti collision stuff.
Although I can see the potential benefit of "bedding" the pads, right off the bat the chick in the video shows her ignorance when she says that rotors should/must ALWAYS be replaced when the pads are.....or maybe she is paid to say that to generate more sales for the rotor mfgr's ?How and Why to Bed Your Brakes

This is not always true, especially during the 1st few years of use. As long as the rotors are in otherwise good physical condition (not warped, burnt or cracked), they can easily be cleaned of excess pad material using various cleaners made for that purpose,
And if they have built up a moderately thick coating of pad material, they can be cleaned by spinning them on a metal lathe (called "turning"), which essentially shaves off a wee tiny bit (think millimeters here) of the existing surface and then polished back to perfection....
Of course this is NOT an option if you were stupid enough to let your pads wear all they way down to the rivets and cut grooves into the rotors or otherwise ignored what should have been periodic maintenance procedures.....
The REAL question here is: will it be cheaper to pay for the labor to turn the rotors vs. replacing them....this really depends on the shop, if they have the proper equipment & the skills to use it, & their labor rates.
In my 50+ years of driving all sorts of vehicles of many makes, models, ages & conditions, I can't recall needing to replace but just a few (5-8) sets of rotors here & there, mostly due to the previous owner's lack of maintenance and/or use of some off-brand, el-cheapo/bargin bin parts....
Usually when a person finds worn pads the rotor is scored, and heated enough to warp. Also, the oem rotors are not as thick as they were years ago so there isn't enough material to turn them without making them too thin.
I agree. I had to replace my front rotors at 12k. I went with vatozone durablast golds. Now I have 50k still perfect.

Using the adaptive cruise control will wear the rear brakes faster. I have a 2018 F-150 and a 2020 Expedition, and I had to replace the brakes on the truck faster than the Expy since I use adaptive cruise control on the truck a lot while my wife (who drives the Expy) does not. It uses the rear brakes more quickly since it primarily brakes the rear brakes instead of all four to increase stability when the computer is controlling the vehicle.

I too have been very happy with Duralast Gold rotors and Duralast Elite Ceramic pads on my 2003 (installed Sept 2015!) and just put the same on the wife's 2016 in December. I've put over 50k miles on the 2003 Duralast brakes. I also bed them in with a few hard brakes when new per the instructions with the parts.
The lane keeping from what I read use's the rears as well.
The factory pads aren't to the metal. They have some pad left. According to Ford in the yellow zone and need replacement. I'm doing the brake job because of the Ford high price, it's cheaper to feed me lunch than pay $150 hr labor. The factory pads shouldn't have done this but their are ridges in the rotor. That's why I'm replacing the rotors/ pads. Mother in laws vehicle and she wants factory stuff. I've found it at Rock Auto for around $250 for factory rotors and pads. Never had knockoffs from them. I have bought from Ford Parts Giant and they are also factory parts but at a higher price. Just did the same thing for my wife's 22 f150. The rotor boxes had the Ford dealers stickers on them from a dealership in California. Contents made in Mexico for rotors and pads. They aren't Chineseium. I guess nothing is made in America but the boxes?
