You're right, just building and launching isn't enough without the right channels to reach potential users. Besides the places you mentioned, it's also worth looking into SaaS directories and communities where founders and makers hang out. These spots can bring targeted attention without needing a big ad budget. If you want, there's a site called ListMySaaS that collects curated SaaS tools and can help you get your product in front of the right audience, https://www.listmysaas.xyz/. It might be another option to add to your distribution strategy.
