Whenever I'm looking for ideas I use Google. Type in "tile foyer", then click on the "image" tab. I got 96.700 results doing that.

Have an on-site consult with a wood flooring Pro (not a big box store). While the exact "style" of you current hardwood may not be available, the Pro will give you a much better idea of what might be possible. Always seek Pro advice...don't just rely on "the contractor".

I say, go for it. The herringbone pattern would be beautiful and would be a nice introduction to your home. I would be extra careful with the layout of the herringbone and the location of the pattern. If you will need a entry rug to catch dirt from shoes the pattern should be offset so that it can be in tact. I would suggest that the borders of the space be laid out in the same linear pattern as the rest of the house but lay the herringbone as an inset to create and some visual interest. I have attached a few pictures for examples.

You have a lot going on in this foyer. Where would you stop the tile? Looks like you have to go down that hallway too. Is that a dining room to the right of the door? Are you just going to make a random tile rectangle in front of the door? The photos don't show us the whole space. I would do the same hardwood floor throughout the house, including foyer. You can't go wrong with a simple classic choice.
