My general advice is not so much about the software as controlling your corporate appetite for customization. There is just an incredible cost to bespoke customization, while the use cases of it are often things like executives' vanity at getting live dashboards or something else. You can have an in-house team build some forms atop a database, and you can even make that work, but only if you rigidly fight feature creep. If you can't fight the feature creep, might as well go with one of the big solutions so that features are reflected in bottom line costs and have to explicitly be paid for out of your business budget, rather than implemented by making requests of your in-house dev team.
