Search the web from Spotlight (⌘ CommandSpace) by entering search text and pressing ⌘ CommandB. The expected result of opening the default web browser (Firefox) and completing the web search occurs. However, the web search engine uses Google rather than the default (DuckDuckGo).
How can I set it so the search is done with my chosen search provider?
macOS 10.15.7
Fire up Safari and check the settings for the default search engine. For me that is google and searching the way you described it for me opens safari (currently my default browser) with a google search.
The option is right there on the first settings tab. I included an image detailing where to find it (sorry for the german):
You can create shortcut to Your page somewhere on Your hard drive (drag and drop address from Your browser). Then use BetterTouchTool http://www.boastr.de to launch this link using global keyboard shortcut.
You can also drag this webloc file to Dock.
Edit: you can also add this webloc file to LoginItems and Your webpage will start automatically when You log in.

You can't change this.
It used to be Bing was the default search for Spotlight, but doing some research I found that of recent, Google has been paying Apple a significant sum of money to be the default search engine.
Apple Doesn’t Truly Let You Change Search Engines
Apple switches from Bing to Google for Siri web search results on iOS and Spotlight on Mac
While using Spotlight for web searching is a nice feature, until the ability to change the engine becomes a reality, the only workaround is to search from your browser.
