Wood, steel, fiberglass? Size? Region of the country? Prehung or door slabs only? I would not buy them from an internet vendor ever but that may just be me.

I always start with TruStyle in Colorado. Only the manufacturer can predict delivery times for entry doors so give them a call.

Last year I had a new fiberglass Therma Tru triple locking door installed, that I love. I will paint it gray when the Spring rolls around. We chose the 1/2 light door; I know you can also get the 3/4 light doors with all kinds of grills. Go on their website and I am sure you can get those double doors as seen in your inspiration picture. Best of luck on your journey.

Wood because we will Paint.
The door my builder says we can get it on time and budget is attached. But looking for more shaker style and thin grills.

This is very local. This past Fall we got Therma-Tru fiberglass French entry doors. Go to a good local builders' supply company and ask them what they can get on your timeline and budget. Often the doors are assembled regionally from component parts.

If painting is the plan why not choose a factory finish on a steel door it will stand up a lot longer than painted wood.

I'll second res_2 then with the Tru Stile recomendation.

Low lead times...Hmm.

For very specific design detailing on double entry doors find the basic door model number and detail it with this tool:

Try doorclearancecenter.com and see if they have what you want. They have wood, fiberglass, steel, and just about any style you can imagine. We got our 3/4 lite 8' fiberglass double front doors from them. Prices were great and the doors were packaged well for shipping. Lead time was about 6 weeks, though. Good luck!
