Hello!
1) Akismet plugin. You need to get a free API key. Just protects from SPAM. Pretty good.
2) Google Recaptcha v2, Invisible or V3. True, there are no plugins for V3 today (12/09/18).
3) Plugin CleanTalk. Protects very well. A month is free, and after a month about 550 rubles. per year per site. If you can afford it, I recommend

if the form is implemented through some kind of plugin, then, most likely, a check is already built into the form and there is no point in bothering with an additional check.
in particular, such a check is already built into ACF. as well as in the FormCraft plugin
