Just to temper expectations a bit, I think Lula has toned down a lot on socialist rhetoric in recent years and has also made a lot of statements indicating he's going to be friendly with the west, while avoiding talking about other socialist countries or things like BRI. During his campaign he even repeated western propaganda that China was occupying Brazil.
Not to mention Bolsonaro's allies controls Brazil's congress
So I don't think there's going to be some socialist revolution here
His vice president is a neoliberal, politically this was a victory for Lula because he managed to associate himself with a part of one of his national political opponents to defeat Bolsonaro, which was necessary because he is still very strong. Honestly, due to Lula's history, I don't see this change in attitude regarding his ideological purposes, he remains the same, with the only difference being that he is keeping with different political sectors of society, I read the entirety of his victory speech, he made this exact claim because he will govern for Brazil and not just for their voters.
The worrying part is really Bolsonaro's allies controlling Congress as you say, this will have to be a priority for Lula to be able to govern, and it could run the risk of creating an economic crisis that can become political.
As for the fact that he is friendly with the West, from what I have seen from his record, Lula is basically a true anti-American, he is more in favor of cooperation with Europe than the US, which is still a victory over Bolsonaro. who would be a kind of American puppet, since he even saluted the American flag, Lula is much more in favor of increasing cooperation with China than Bolsonaro, Lula is more in favor of decreasing cooperation with the USA than Bolsonaro , which is still a victory for the BRICS, regardless of whether it is friendly with Europe.
Also, are you Brazilian?
