Porcelain is a tough tile which will not crack or break easily. they are very long lasting. vinyl is out dated and just doesn't look good. Your other option should be ceramic tiles. So it should be between ceramic and porcelain. I'd still recommend porcelain but ceramic is cheaper, that's the biggest advantage of ceramic. I bought these porcelain tiles two weeks ago, they look lovely. beautiful hexagon porcelain tiles

Ask your self if the kitchen is actually a good kitchen….. if you need a utility room next to the kitchen for additional refrigeration or storage or additional work surface then it’s not a good enough kitchen for you. Ideally the utility should be just a laundry room in which case it’s best near the bedrooms upstairs or at least near the bottom of the stairs.

We had our bedroom floor done 3 years, it’s about 27sqm. It only cost c1k but we didn’t need sound insulation. The guy was an antique furniture restorer who started refurbishing floors as a sideline and i suspect he seriously undercharged us..We also didn’t need much in terms of repair work, all boards were sound and only 1 had been replaced at some point in its lifetime, you may also find holes where central heating has been installed or gaps under skirting etc i think you need to consider whether you’d be happy with all the dents as pine is such a soft wood. We hung new curtains days after the floor being done and the ladder (sat on a towel) created dents. We put furniture pads under everything but have had no need to move the furniture since but i suspect it has big dents everywhere! It's fine for us jn a bedroom but not sure if i could cope in a living space

I hope I am assuming correctly from the window placement that this house is detached? Maybe its a bit simplistic but swapping the kitchen with the reception room and extending into the left corner would give you a floorplan closer to what you had. You could also open up the wall between the dining room and the current reception room which would give you a decent sized kitchen diner. It would be good to see a floorplan of upstairs too. There is no question that there is less floorspace than where you were before. You will probably need a downstairs WC too maybe the current utility room?
