David Beckham got the best possible deal and as per Forbes he earned $255 million while playing for the Los Angeles Galaxy (and that was one decade ago, when the USD had more value). The initial deal was worth $32.5 million in 5 years, but stock option clause made him insanely rich. But the case with Ronaldo is different. He is part of the Saudi bidding team for the 2030 FIFA World Cup and has already taken up residence in Saudi Arabia along with his partner Georgina Rodríguez. And there are rumors that he may go for the Saudi citizenship soon.
I highly doubt that he would be getting Saudi citizenship, that is basically a rumour to make Saudi Arabia to look better, just the fact that you can't live with your girlfriend there, and he was given a special consideration, when any other person can't, is the proof that he won't be doing it.
In any case, Beckham deal was basically filled with incentives, whereas Ronaldo straight up gets this much money, they are not the same thing at all and it would not be considered the same now. Plus Beckham didn't get it in a year, he got it over course of many years, Ronaldo is getting a ton of money if we are looking at the whole thing and maybe even after that.
