Not two politeness levels but two directions — 尊敬語 lifts the action of the person you are describing, 謙譲語 lowers your own; whose action it is decides which one you may use, so neither is ever the "politer" choice.
丁重語 raises nobody inside the sentence — it lifts the tone toward whoever is listening — while 尊敬語 raises a person named in it; so 参ります needs no esteemed destination and stands equally in 駅に参ります and 田舎に参ります.
Lookalikes
社長が呼ばれた is honorific and passive at once, and only the rest of the sentence separates them — the esteemed person as the が-subject with no に-agent in sight reads honorific, a に-agent forces the passive (部長に資料を読まれた), and an inanimate subject leaves only the passive.
Combines with
お〜になる is the productive wrap for a verb you have memorised no special form for; a memorised form always wins over it (×お見になる, ご覧になる), and れる／られる covers the verbs whose stem is too short for the wrap (×お出になる, 出られる).
The request face of the same wrap — お待ちください asks the esteemed person to act, お待ちになる reports that they do; ください never states, and になる asks only through a further ください (お待ちになってください), which is stiffer than the short form.
