This sounds like a true, spiritual struggle for you. I would encourage you to speak with your priest about that which ails you. Take what you have here, weight what we say, and take it with you to him, if it helps. But this, I believe, is spiritual, and your priest should be the most important person involved in this for you.
That said, you raised a few reasons your like Catholicism. I'd like to look at those.
1. Options to receive Eucharist daily;
Not really an option in most Orthodox parishes in the US, granted. That said, we do have a full cycle of services that should be done at least on Saturday night/Sunday morning. I don't know about you, but I gain just as a much a spiritual blessing from the Vigil service as I do from Liturgy (save the actual reception of the Eucharist, of course). I just love it.
2. Strong private devotions outside of Sunday liturgy/Mass;
There are many private devotions in the Orthodox tradition. The praying of akathists and canons, molebens, etc. Also the use of the Jesus Prayer or modifying it for other saints (nothing wrong with using the chotki to pray "Most Holy Theotokos, save us" or "Holy Father John, pray to God for us," etc.
Many western devotions have also been baptized by the Western Rite Orthodox, perhaps that is something you would be interested in exploring? Where is the nearest WRO parish? There aren't many, and so maybe it couldn't be a frequent trip for you, but it might help.
3. Admiration of certain Roman Saints;
This can be problematic. That said, I know Orthodox who have a veneration of some Western saints. I know Orthodox who love St. Francis of Assisi, or St. Bernard of Clairvaux. There are also many pre-schism Roman saints that are beloved by Orthodox, like St. Patrick of Ireland, St. Brendan the Navigator, St. Sebastian, St. Alban of Britian, St. Augustine of Hippo, Pope St. Leo of Rome, Pope St. Gregory of Rome, Pope St. Martin of Rome, St. John Cassian, etc.
4. Adoration of the Eucharist;
Why do you want this? Ultimately, this issue comes down to the purpose of the Eucharist. Orthodox do worship and adore the Eucharist in the Liturgy. At the same time, Christ says, "take, eat" and not "take and look at," (to risk being a little blunt). I think this is ultimately something theological, and so I'd like to hear your thoughts on Eucharistic Adoration and why you miss it.
5. Family ties
I can't say much about this one, either. At least your family is Roman Catholic. They at least have an understanding. My parents have a Protestant background, but are not religious. They don't get me at all. I can't really relate to them in a lot of lifestyle type of issues. They don't get the importance of the daily services, the Liturgy, regular private prayers, fasting, etc. I hate using this, but...it could probably be worse.
I hope that you find where you should go on this journey.
The LORD bless thee, and keep thee:
The LORD make his face shine upon thee, and be gracious unto thee:
The LORD lift up his countenance upon thee, and give thee peace.
