I'm trying to turn off my start-up sound on my macbook pro. I am running Catalina. The option for "play sound on startup" does not appear as one of the options in Sound Effects. Any suggestions?
MacBook Pro (2020 and later)
you can try opening terminal (in Applications > Utilities) and copy and paste "sudo nvram StartupMute=%01" without the quote marks into terminal window and press "return". enter your mac's admin password when prompted and press "return". then restart your mac to test.

Thanks for the suggestion - I had found that article but just doesn't apply to Catalina unfortunately.
Actually, it does; however, it was a bit more indirect than I thought and I should have given you the direct link instead. Sorry!
In that article, it had a link "sold between 2016 and 2020" which would take you to a How-To Geek page that pretty much offered you the same solution as jefferythefrog gave you. It was in the "How to Disable the Mac Startup Chime" section. I just thought you may benefit from a screen shot of the command.
Apple made this easy with macOS Big Sur, but with earlier versions, give this article a try:
before i posted, i checked my catalina boot drive. as the OP mentioned, the "play sound on startup" option is not available, hence the terminal command i provided. :)
Your reply to the OP was spot on! I just offered an article for their reference.
sorry if i sounded combative. i just thought you missed the "not available". i mean, we all miss things every now and then, right? :)
Didn't take it that way at all. No problems. Glad to have you here, and appreciate any comments.
Thank you! Problem fixed.

you're welcome. happy to help.
Hi there, I see - I didn't follow the link originally as I should have, but now see the extensive detail there. Thanks so much! I appreciate the support/information!
You're very welcome!
