First, Duckduckgo is an excellent search engine, but a pretty lame browser.
It used to be great, but a few years ago they changed it and it really sucks in comparison.
Go ahead and use your new device, because that will be faster and easier.
Be sure that Airplane Mode is on, SIM card is out, and go through NoRoot intensely.
After you get NoRoot set up, turn Wi-Fi on.
Download F-Droid. Use whatever toilet biscuit excuse for a browser that is built in.
https://f-droid.org/
Once that is downloaded and installed, get rid (clear all data and disable/uninstall) of whatever browser you had to use to get it (Google, Chrome, or whatever stock mess it came with).
Set up F-Droid, going through all the settings.
(There will be more to this later on, because there are other app repositories to add.)
F-Droid takes a bit to set itself up, there is a catalog of thousands of apps.
Afterwards, use F-Droid to download the following:

And yes, there is more- but you already have enough to do at this point.
There are multiple browsers here, all based upon Lightning but with different options.
Reason being is that you can set a browser to automatically open on a certain site, essentially making that browser an app for that site.
I use Midori just for Android Forums.
Also, I don't know exactly what you want in a browser, so now there are options.
There is PLENTY of room for all this, and because the apps are so small there is no reason not tohave them all.
After you set all these up, go back into F-Droid and get ALL the rest (16) of the Simple Mobile Tools apps.
Yes, all of them.
They sync with each other well, and you will need utility apps if you are not going to use stock or Google apps.
There are going to be issues that anyone used to using Google poop is going to be annoyed with, and things may start out slow.
One thing is certain, without Google poop my devices run better.
Open your Developers Options as well, because you may need to make some adjustments there.
Let me know how it goes so far, and if you want more.
Also, depending upon the age of the device (6 months, a year and a half?) it nay constantly badger you about updates and crap like that.
Just let it do it this once, as it most lijely is only going to update the Google junk you don't want.
It is tedious, but I did find a way to revert these crAPPS back to their original (stock to the device) sizes and versions.
You will need (and you want this anyway) the UpToDown app for that.

I know this is a lot to dump onto you all at once, but renember that I spent 3 hours in the parking lot at Wal-Mart immediately after I purchased my device.
That was all before I inserted my SIM or allowed it to connect to the internet.
When I got to that point, I used their Wi-Fi, lol.
You will need a better laucher, because stock apps cause bowel obstructions.

(Probably the highest recommended laucher on Android Forums.)
Personally, I use KISS.
After you use it (about 12 hours), it learns your habits and most controls are had with one to three button pushes.
Like when I want the apps setting page, I touch the screen to reveal the keyboard, type "A", and then "apps" appears and I select it.
Or I can find the app in the app drawer, long press it and a menu comes up.
It is very different, but like I said- after 12 hours it won me over and I hate all other launchers.
Nothing is faster or easier.

Back to those browsers, you can set the home page to be any website or search engine that you like.
If you have certain settings that you want in your search engine (and you DO), then get the bookmark information, and copy/paste it into the proper setting on the browser.
I included Telegram in that list of apps.
I find that social media is basically a turd on a stick, so Telegram is a great communication app.
Also, if you like, I could give you a link that would allow us communicate one on one at a level not really possible on this forum.
In fact, phone calls, videos, pictures, and all that is free on Telegram- unlimited and without ads!
