I just found out about helm-surfraw by reading Tuhdo's Helm guide.

For those familiar with Helm, is there a way for me to call helm-surfraw on a selected region, i.e., using the region as the input for helm?

Example, let's say I'm writing a text and I want to find a synonym for a word. Instead of calling helm-surfraw, typing the word and searching, I'd like to mark the word and have helm automatically take it as an input.

With latest version of Helm (see this PR), if you select a region before calling helm-surfraw, the text in the region will be used as the "default" argument. Saying you have selected "hello world" then typing

M-x helm-surfraw RET RET google RET

will Google "hello world". You can also use M-n (next-history-element) to put the default argument to minibuffer so that you can change it if you want.
