WordPress admin display post type tags as checkbox

I used WordPress ACF plugin to created a post type called resource, also I created two tag categories named resource-type and resource-topic, I can added in those tags in the post by the enter certain key in input box, but if the input is mistype, a new tag will auto added in the list, this is not what I want and I think of make the tags as checkbox so that it would easily know what tags is available and reduce the mistype error, is it possible to change like this way?

Is There a Difference Between Taxonomies and Categories?

I’ve been reading the codex for WordPress closely and am confused about the vague definitions between what a Taxonomy is and what a Category is. For that matter, term is also a word that is used in the description of Taxonomies, but seems used in a manner that hints that it isn’t solely limited to a Taxonomy.
