I don't think that there is "one solution fits all" in this case. Personally, my websites have never been hurt with internal linking. However, keep it natural. Apart from links within the articles, you can always use "Related articles" section for some internal linking, or be creative with tags. Sometimes I use tags as categories, with each tag having a separate page with related content. Then you can also add something like "More articles like this in..." at the end of an article, and then list all the tags the item is in. If you've done proper siloing, then you will strengthen your categories, which will in turn strengthen your articles/posts/items. And it's all natural.
Also, whenever possible use breadcrumbs.
I don't worry too much about it, just trying to keep it natural and never had any problems. Hell, some of my category pages were ranking in top5 for 200k monthly searches (no buying intention) without a single external link to the page. But every single article (at least 60) in those categories is linking back to the category itself.
I know that many will argue that tag/category/breadcrumbs links are not as strong as the links within the articles, but they do provide some juice, and that can sometimes be enough. I am sure Google knows how to differentiate between various internal link types, and will probably never punish you for tag or breadcrumbs or related items links.
