Is the word sugestões the same in Brazilian and European Portuguese?

Yes

The spelling, meaning, and grammatical function of "sugestões" are identical in both Brazilian and Continental Portuguese. The only differences are in pronunciation and prosody. In Brazilian Portuguese, the vowels are generally more "open" and the rhythm of the speech is more syllable-timed (more musical). In Continental Portuguese, vowels—especially unstressed ones—are often more "closed" or even reduced/devoiced. Additionally, while the "s" at the beginning of this specific word sounds the same in both, the overall cadence of the word in Portugal tends to be more stress-timed, making the word sound more "compressed" compared to the Brazilian pronunciation.
