Both "sj" and "g" sounds are common. Some people prefer the latter because of the Greek origin of the word, but the same is not true for words like chirurg, which is pronounced as sjierurg. English pronunciation is different on 2 counts: the first syllable is stressed (in Dutch the last), and the ch is rather more like a k.
To add to this, here is a video in which you can hear both pronunciations: https://nos.nl/video/2048055-minimumtarief-voor-zzp-architecten.html
Cool! Thank you both, for the explanation and the video. Here is a video of renowned architect Rem Koolhaas. The narration in the video is in English, but most of the video is in Dutch with English subtitles. I put Dutch text in the comments section below the video with time markers for each segment so that anyone learning Dutch can follow along. The series is called Dutch Profiles.
