Question about hardwood floors (Long)

Through no fault of my own, my house has two different wood varietals running two different directions; one stained and the other unfinished. The kitchen, dining room, living room, foyer are an open floor plan. The living room/dining room area was dark stained pine (we had no idea the wood type till recently). The kitchen area, half bath and pantry were all tile, but a previous owner had ripped this up. They had install white oak, but left it unfinished.

The planking of the dark stained pine runs east to west upon entering the front door. The white oak in the kitchen runs north to south. The two different wood varietals come together at a good point between the kitchen and open dining room/living room area.

We initially thought of staining them different colors because the rooms are different and it would naturally divide the rooms up and allow for a different feel in the kitchen as opposed to the dining room/living room area... but were told this was bad.

From a resale perspective, we were told that a uniform look will add more value to the home. The white oak is very nice and clean looking. I sanded a bit of the dark stain off the pine today and it is very knotty. I like the look, but the two woods obviously clash.

We have a hardwood guy coming tomorrow and he thinks he can match up the wood (through staining) but I think they will look A LOT different. It's a big gamble with the money we are paying. We are considering cancelling the sanding/staining/poly and instead ripping up the pine and just running uniform white oak throughout the downstairs and then staining it all the same but this makes the price jump up a lot more.

My SO thinks we should hear the contractor out on matching it up and possible just save the money on rip-up and install. While I'd pull up the old pine, installing and purchasing the white oak would add a good amount to what we thought the job was going to cost.

Anyone have experience with a similar situation? Will having two different woods, running two different directions be a huge issue if we can get them looking similar through staining?
