This package doesn't seem to be very well maintained,(source has deprecated Meteor code) and warns This package is designed primarily for correctness, not performance. That's why it's aimed at counting smaller datasets and keeping the count instantly up to date. Is this the best choice?

I agree completely, this notice also make me hesitate about using it. I will try to find another way of getting reactive count value.

We could simplify it like this:

const filters = new SimpleSchema({
  "shops": {type: [String], optional: true},
  "tag": {type: String, optional: true},
  "query": {type: String, optional: true},
  "visibility": {type: Boolean, optional: true},
  "details": {type: Object, optional: true},
  "details.key": {type: String},
  "details.value": {type: String},
  "price": {type: Object, optional: true},
  "price.min": {type: Number},
  "price.max": {type: Number},
  "weight": {type: Object, optional: true},
  "weight.min": {type: Number},
  "weight.max": {type: Number}
})

Meteor.publish("Products", function (productScrollLimit, productFilters) {
  new SimpleSchema({
    productScrollLimit: { type: Number, optional: true },
    productFilters: { type: filters, optional: true }
  }).validator()
...

I think it should work not only in validationMethod. see docs. We don't need try/catch. Need tests

I already tried this and I learned, that we can not completely substitute check() with SS validator, because check package will throw error "not all arguments of publication are checked with check()".
And I like more verbose schema in my case, because it shows full structure of productFilters argument. Don't mistake ValidatedMethod with publication function. You are offering use the same strategy and imho this is right way, but there is no ValidatedPublication package for now, read here

Try/catch we need, because validate() throws ValidationError and inside publication will fails silently without and log message (for me that is strange). We need throw Meteor error again to stop continue publication with wrong format of arguments

I have a feeling that we can't use audit-arguments-check and SS.validator() within one app. here

We can in the way I did. audit-arguments-check only need that all publication arguments were checked using check(). After we can validate structure of any argument using SS validate() and throw error if it's wrong
