This is a main function, ifAnyOf, and a suite of demo predicate LAMBDAs to facilitate building include statements for FILTER (and other uses). Trying to come at this from a functional programming perspective, I'm basically attempting to build a liftable OR function that can be implemented with helper predicates to read like an English sentence like this: ifAnyOf <column> hasProperty(x). The predicate LAMBDA in this hypothetical example builds a conditional on its parameter x, then returns a LAMBDA that will take <column> as it's parameter.

Excel Formula:
=LAMBDA(col_array,preds,
  REDUCE(
    FALSE,
    preds,
    LAMBDA(acc,pred,
      (acc)+pred(col_array)
    )
  )
)

Examples to follow.

Predicate LAMBDA examples used above:

isEqualTo
Excel Formula:
=LAMBDA(vals,
  LAMBDA(val,
    REDUCE(
      FALSE,
      vals,
      LAMBDA(acc,curr,
        (acc)+EXACT(val,curr)
      )
    )
  )
)

isGreaterThan - this is strictly greater than, feel free to create your own isGreaterThanOrEqualTo
Excel Formula:
=LAMBDA(val,
  LAMBDA(vals,
    vals>val
  )
)

isLessThan - this is strictly less than, feel free to creat your own isLessThanOrEqualTo
Excel Formula:
=LAMBDA(val,
  LAMBDA(vals,
    vals<val
  )
)

isBetween - this is inclusive of the endpoints, not strictly between.
Excel Formula:
=LAMBDA(vals_1,vals_2,
  LET(
    v_1,IF(TYPE(vals_1)=64,vals_1,CHOOSE({1},vals_1)),
    v_2,IF(TYPE(vals_2)=64,vals_2,CHOOSE({1},vals_2)),
    lower,MAP(v_1,v_2,LAMBDA(_1,_2,MIN(_1,_2))),
    upper,MAP(v_1,v_2,LAMBDA(_1,_2,MAX(_1,_2))),
    funcs,
      MAP(lower,upper,
        LAMBDA(low,high,
          LAMBDA(val,AND(low<=val,val<=high))
        )
      ),
    LAMBDA(vals,
      MAP(vals,CHOOSE(SEQUENCE(ROWS(vals),1,1,0),funcs),
        LAMBDA(val,fn,fn(val))
      )
    )
  )
)

startsWith
Excel Formula:
=LAMBDA(vals,
  LAMBDA(val,
    REDUCE(
      FALSE,
      vals,
      LAMBDA(acc,curr,
        (acc)+(EXACT(LEFT(val,LEN(curr)),curr))
      )
    )
  )
)

contains - searchs for matching substring, escaping wildcards; if would like to use wildcards, remove that bit of the function
Excel Formula:
=LAMBDA(vals,
  LAMBDA(val,
    REDUCE(
      FALSE,
      vals,
      LAMBDA(acc,curr,
        (acc)+
        IFERROR(
          ISNUMBER(
            SEARCH(
              IF(
                isEqualTo({"*","?"})(curr),"~",
                "")&curr,
              val
            )
          ),
          FALSE
        )
      )
    )
  )
)

either - this allows chaining multiple predicates on the same column
Excel Formula:
=LAMBDA(
    pred_1,[pred_2],[pred_3],[pred_4],[pred_5],
    [pred_6],[pred_7],[pred_8],[pred_9],[pred_10],
    LET(
      omits,
        CHOOSE(SEQUENCE(10),
          ISOMITTED(pred_1),ISOMITTED(pred_2),
          ISOMITTED(pred_3),ISOMITTED(pred_4),
          ISOMITTED(pred_5),ISOMITTED(pred_6),
          ISOMITTED(pred_7),ISOMITTED(pred_8),
          ISOMITTED(pred_9),ISOMITTED(pred_10)
        ),
      pred_ct,REDUCE(0,omits,LAMBDA(acc,bool,acc+NOT(bool))),
      preds,
        CHOOSE(SEQUENCE(pred_ct),
          pred_1,pred_2,pred_3,pred_4,pred_5,
          pred_6,pred_7,pred_8,pred_9,pred_10
        ),
      preds
    )
)
