Hey Anahita!
I've been using User Testing for web message testing + market research for a few years now, but their packaging model + how its changed over the past year have me looking elsewhere. It should technically do everything you need, but the user experience is not the best compared to other options + theres a lot lacking. For alts, I've been looking at and have had good trial experiences with Dscout as well as Outset.ai.
The UX research team at my company has Maze. It seems promising and like it'd work well for integrating with Figma, however the way it functions doesn't make it good for testing stimuli that aren't a prototype. Displaying videos or image stimuli and trying to collect verbal responses to questions about them just doesn't work easily. It's not the best for marketing research, but seems great for user research.
Wynter might be a good option for you if you want to pay as you go vs. doing a larger annual contract. Its been a bit since I've used them, so unsure about Figma, but I was happy with their output the last time we used them. Also unsure on video/audio recording, but still wanna throw this one out there as an option.
Qualtrics has their own unmoderated tool they launched recently, but its still super basic so I wouldn't recommend it till its more developed.
