With all due respect, being "from the other side of the pond", I don't think you understand the U.S. well enough to be commenting. For example, California is both the largest producer of food in the U.S., and the state being most significantly under-represented in all three branches of government.
The U.S. is also, easily, the most volatile (extreme partisanship) country of comparable rich, democratic nations. The system we have is pretty unique in its attempts to bend-over backwards to boost rural voters' importance, and we're worse off in virtually every "bad thing" you mention than countries that don't do this.
Centralization? Our president is independently murdering people in the carribbean, demolishing an entire wing of Whitehouse to build himself a new ballroom, independently changing funding (i.e. has hijacked the power of the purse from Congress), is independently sending in the U.S. military into states run by his political opponents against their will, pardoning violent criminals who supported him (one of whom was caught plotting to murder the House Minority Leader, Hakeem Jeffries), etc.
Rural areas will stagnate / people will move away? Dawg. That's already been happening despite the political concessions they've been given. That ain't the problem.
Urban house prices skyrocketing? Happening. NYC is among the least affordable major cities on the planet.
Crime rate? Generally highest in the places where we give disproportionate political sway to.
Are you suggesting the 66x more representation Wyomingers get over Californians in the Senate isn't enough? Is the ~3.5x more voting power they get in presidential elections not enough? What is a fair "middle ground" in your estimation? Because it feels extraordinarily unfair in the exact opposite direction, to me.
(Editing to add): It's also worth pointing out that this delta in voting power is much more extreme today than it was when this system was designed. In the 1800 census, the most populous state, Virginia, had 885,000 people, around 15x more than Delaware, the least populous state. Today, California has 67x the population of Wyoming.
I am but stating the dark side of equal voting power when you elect representatives per "region" dictated by the population they have. It is meant to be a warning, something to bear in mind when you do attempt to change the system you have.
I am not arguing in favour of what you have right now, hence the middle ground point at the end.
Regardless, my understanding of the US is not important. What is important in my comment is my understanding of what you don't do, and potential footguns.
A good middle ground would be to still have it entirely dictated by population (I understand this seems contradictory but hang on). But, in order to prevent votes from low population regions from being useless, your system uses "preferential voting". Most other countries do not do this, hence my previous comment. The key here is that at a national level, politicians still need to value less populated regions, because at least a percentage of their votes came from someone who voted in an order that still got them a seat (even though they weren't the top pick). Given rural regions have less seats to vote for, this vote would likely come from someone from the country side.
This solution however is only important when you do have more than 2 parties. If you don't do this, having more than 2 parties would be moot in these regions, because they need to vote strategically if they want representation. And 90% of the time that means your vote is limited to only one of the top 2 parties (as perceived by national polls before voting day). This is yet another dark side of the system my country does have, it incentivizes the status quo to prevail, even when your current leaders are a bunch of corrupt fellas.
