Vaultwarden in enterprise

Hello,
I know vaultwarden for a while but I was wondering about implementing it in my company.
We are about 300 people and let’s say the IT budget is more than limited, do you think the instance would hold? I think that the 300 people will not use the tool to its full potential but only the so-called technical teams. What do you think, what makes me fear the most is that sqlite explodes.
Why I say this, because the first need is that we want to share passwords in team and the licenses are very expensive…

Thank you all for your opinions.
