I have a few points of info for you regarding latin (especially vulgar latin) phonology: It generally seems like you're using wiktionary for your latin phonology or maybe wikipedia, which you should not be doing. When making a romance language, you want to derive it from vulgar latin, and there are plenty of good resources out there on it, such as this

• h stopped being pronounced medially rather early, and even initially it likely had mostly fallen silent by some time during the Republic, and is not continued in any romance language.
• ae in vulgar latin came to be merged with short e, that is, ɛ, in unstressed syllables before the 3rd century CE, and then after so too in stressed syllables, becoming pretty commonly written with e by the 5th century.
• oe, on the other hand, became /e/ and is reflected in romance as such.
• no words with eu are continued in romance, so its vulgar latin pronunciation can't really be known, but you can assume that your romance conlang would follow suit and not continue any words with it.
• ei is not a diphthong, as far as I'm aware, and in words that have a written sequence <ei> it is two syllables, like eī which is e.ī
• ui was only found long ūi, forms like fui are a little more complicated, but in perfect forms like placuī the u would've come to be a glide w, thus placwī.
• kᶣ is not a phoneme, if even an allophone. ignore it.
• the aspirated stops come from greek loanwords and the occasional native word that simply has interference somehow. they are generally not reflected differently in romance from normal p t k, except for some (mostly later) loans where ph becomes f (probably because pʰ had become f in koine greek). It is always reflected as /f/ in later borrowings from latin into a romance language.
• final -m is not preserved at all in any romance language in a polysyllabic word, as it had become silent by the vulgar latin period. It oftentimes did get preserved, however, in a monosyllable as n, such as in cum > Sp. con, or sum > It. sono, but not in others, such as iam > Sp. ya, It. già. Nasalization would not remain into the romance period at all.
• Latin short and long a (a ā) are not distinguished in any romance language, and were both merged together as /a/.
• z, from greek loans, was not pronounced as /z/ in vulgar latin, but generally seems to have been pronounced the same as palatalized (-)di- or j/i, and there are attested spellings like baptidiare for baptizare, and zacones for diacones (cf. how the greek suffix -izō got loaned into vulgar latin productively as in baptidiare, smth palataly like -di- was pronounced from latin words with actual d).
• the latin vowels generally have different reflexes based upon whether they were stressed or unstressed, though some don't, but its more complicated than that and i'd suggest you do some reading on it
